They just called me and I couldn't answer at the time. When I called the number back it said I had reached a number that was no longer in service and it had only been 15 minutes since they had called me!!

2009-01-29 23:05:06 UTCJoseph

I have filed a complaint with the FCC about this company. It is a scam. They have no idea who they are calling, even if it is a legit company, which I seriously doubt. I am an attorney in Tennessee and am considering legal action if I can find who they are and where they are. I will not return their calls at all; this conduct is total harassment.

Answered the phone and said "hello" but all I got was silence.

2008-10-03 03:13:51 UTCFred

They left an unintelligible message about a past debt. Sounds like they are just trying to shake us down. I have vonage, I sure wish they would have it where I could block specific phone numbers.

2008-08-11 21:54:54 UTCNo

I received calls from this number and from some unlisted numbers and they leave a message saying "this is an important message from NCO Financial Systems Incorporated... This is an attempt to collect a debt.... Please call Mrs. Carter at..." and then they give me an 866 number. I've tried calling once, but it seems to be after business hours. I'm suprised there are this many people who have received the call but without a message. They always leave a message on my cell phone, even if it comes in as unlisted. And it's always the same recorded message.

2008-07-23 19:11:03 UTCWayne

Left message to call NCL...tried to call twice and was put on long hold both times...I hung up.

2008-02-26 14:46:58 UTCBarbee

They called, didnt answer, they didnt leave a message. When I call the number back it gives me an "off-the-hook" noise.

2008-01-17 22:27:40 UTCkh

if calling my number please leave a message

2007-12-06 01:10:42 UTCJOHN

HUNG UP AFTER I PICKED U MY CELL PHONE,CALLED THE NUMBER AGAIN GOT ENGAGED TONE

2007-11-30 18:36:06 UTCalisha

jnk6476- Your grammar sucks.

2007-11-09 23:30:01 UTCLouise

They did not leave a message..

2007-10-13 18:59:17 UTCdontanswer

They call here, but I never answer. I only accept calls from people I know.

2007-10-03 00:29:00 UTCPatricia

A recorded male voice said he was calling re: an important business matter in his office & it wasn't a sales call. Requested a return call to 866-821-5890 which is a collection agency for the controller's office for the Sales Tax Division of the State of Texas.

2007-09-26 19:04:12 UTCChristine

Frustrating...........they just call and hang up...I'm glad it is a work phone not a home phone......

2007-09-26 17:44:25 UTCcarol

annoying calls every few days. No ID no answer. Any suggestions on how to end their calls?

2007-09-05 21:09:40 UTCDoug

Called my Sprint Cell Phone. Sprint sold them my number. Sprint billed me for the minute it took me to hang up.

Recorded message said they had an important business issue to discuss.

2007-08-15 01:25:40 UTCjnk6476

Another piece of advice, If you call them up cussing and carrying on like an imature jackass do not expect them to go out of there way to stop the calls.

2007-08-15 01:17:15 UTCjnk6476

Just a little advice. When you purchase a new cell phone ask to be given a number that has never been used before, this includes house phones. After each visit to a doctor Always check with your insurance to make sure that it was billed correctly. It is the PATIENTS responsiblity to ensure that that the claim was filed. You can ask your insurane company. The hospitals make you sign a paper stating you take that responsiblity if insurance is not filed or if they do not pay. Alright people you are all adults. You all need to just answer the phone. You can stop the calls with one call

2007-08-15 01:06:42 UTCjnk6476

If OSI calls your home it could be for a couple reasons. OSI could have a wrong number, the numbers they have are numbers reported to them from either a hospital or physicians office. These are numbers that were provided as a contact by the patient.Or it could be that your insurance did not get billed due to the fact that the hospital did not share the info with the physcian,so you get sent to collections. Or you have a medical bill that slipped through the cracks. Or your just a dead beat that does not care about there credit score. And YES some hospitals and physcian groups report you to the credit bureau. Osi only reports if hospital says too. When they call they cannot leave a detailed message its against the law. A little law called HIPPA, Its personal medical information. You would all whine if they disclosed that information on a machine and you played it in front of your neighbor. Quite acting dumb and answer the phone, your only hurting yourselves. OSI IS A COLLECTION AGENCY Its real not a scam.

2007-08-14 19:38:44 UTCBetty

They called my cell phone and left a computer message. Did not tell me what it was about. VERY annoying!

2007-08-12 22:57:46 UTCMeMeHootieB

Caller I says OSI 262-787-4163. I didn't answer. They didn't leave a message.

2007-08-06 15:30:38 UTCFrank

Just got a call from this number. Didn't answer. I don't answer unknown numbers from my cell phone. I have Sprint if that matters. From the looks of it, I'm not wasting my time trying to figure this out since I owe nothing and wouldn't have the concern about a collections agency. Glad I stumbled onto this site. I will be providing info on here as I receive unknown calls to help everyone out too. Thanks.

2007-07-19 21:04:49 UTCHasani

I receive a call from this number EVERY SINGLE DAY!

2007-05-24 01:34:00 UTCtech1

udp flood their phone lines with repeat dialing it will take their phone system down.

2007-05-18 16:52:06 UTCOlga

I am being called every day on my cell. I am going to put a block to this number 262-787-4163. There is also 262-646-3036 and 614-717-7395.

2007-05-15 18:32:03 UTCCJ

This number keeps calling me and hanging up on me when i answer it.

2007-05-15 18:06:53 UTCP

they called and when i answered hung up. awesome.

2007-05-15 18:01:42 UTCHerp

Is it only T-Mobile Cell Phones??

2007-05-10 15:44:25 UTCSonia

I went to this web site ---> osioutsourcing.com
This text appears at the top of the page "If you are a consumer with a question or comment about your account, please call our consumer hotline at 1-800-962-5191."
I told them to STOP CALLING ME. The lady was very nice and said that she put a "block" on my number. I didn't have to leave my name either.
We'll see if that works!!

2007-04-24 21:56:46 UTCAndy

Aboutonce a week, I will get a call from this number. Initially I would answer and a recording of:

Please call reference Branch Number?

Now, I don't answer but the recording will leave the same recording on my voice mail.

2007-04-19 14:08:07 UTCscm

they leave a voice mail that says to call an 800 number - I get a message from them about once a week.

2007-03-30 08:30:09 UTCcd127

Message left to call their toll free number 888-850-6428 ref Branch 49

2007-03-19 13:48:23 UTCgeorge

if you don't list company name i don't answer

2007-01-25 10:47:00 UTCC N

Just a important message and call them back\

2007-01-20 04:29:29 UTCTodd

They call and call and call and do not leave a message. A good baseball bat would solve this problem. I have asked them to stop calling but they still continue. I have no idea what they want.

2007-01-03 12:58:30 UTCBruce

Annoying & anonymous call. I forgot how to add someone to my Blocked-Call list. AHow do I do that?

2006-12-14 18:18:13 UTCJ

They called and when I answered, they hung up. I tried calling back and only got a busy signal.

2006-08-31 00:40:20 UTCMargaret

They call my cell phone regularly, leaving no message.

2006-08-30 01:03:37 UTCSteve

They call every day and leave no message.

2006-08-29 23:38:27 UTCMatt

Called and left no message.

2006-08-29 01:00:24 UTCMarcos

Call my cell phone often and leave long annoying non-sense static sounding messages.

2006-08-28 21:21:54 UTCTony

each of us should volunteer to go to one of these locations and show them how a t-1 line can sooooo easily be cut.

2006-08-28 17:11:53 UTCAmy

I received a call from this number on both my cell phone AND my parents home phone. The message I received stated that they were call regarding a personal business matter and gave me an 800 number to call. I have NO past due bills and sparkling credit. I did not have a chance to write down the 800 number but tried to call back this number several times and it is busy!

2006-08-28 16:26:05 UTCSara

Just got a call- They did not leave a message nor did pick up when I called back.

2006-08-28 15:14:32 UTCAugtan

They call and do not leave a message! When I call back I get a busy signal. Who is this? It says Milwaukee, WI on caller ID.

I get calls from this number EVERY Saturday morning. When I call it back, I get a constant busy signal. They have been told repeatedly to stop calling!

2006-08-26 13:36:57 UTCCP

They call my cell at least twice a day if not more every day...including weekends!! Early morning and even late evening. They never leave a msg. I send it straight to voicemail now. It is very annoying. This is ridiculous!!!!!

2006-08-25 15:16:09 UTCpc

They repeatedly call my number. Ditto all the other comments.

2006-08-25 13:34:15 UTComar

They called my cell in the morning, asked for me by my first name, I asked who was calling and they immediately hung up.

2006-08-24 23:31:23 UTCJohn

They called and when I answered it went to a call them then theyanswered that an operator would be with me in a moment. 3 minites later they hung up. I don't owe any outstanding debts!

2006-08-24 23:31:10 UTCKaren Felek

No message. I just wanted to see who it was that called. I don't answer any numbers I don't recognize. The called I.D. said "Unknown". I am registered with the National Do Not Call registry.

2006-08-24 18:13:34 UTCV

They call, leave a voicemail in English and also in Spanglish. The message says to call some 800 number which I 'Skyped' and found it goes to OSI Collections.
Evidently they think someone who previously had my new phone number owes them money.

osioutsourcing.com

OSI and this number is a collection agency out of Colorado that companies hire to outsource their collections. They don't leave messages and call all the time/many times a day.

2006-08-23 23:05:13 UTCMatt

They call every day about 8:15 in the am. I don't answer, they leave static for a msg. This is annoying since I am on the Nation Do Not Call Registry.

2006-08-23 15:19:53 UTCTony

Call every couple days and when I pickup the phone, it hangs up. They don't leave a message when I miss one of their calls. They are calling my cell phone and it is ridiculous.

2006-08-23 15:15:35 UTCClint

I think that this is a automatic dialer that tells other companies that you picked up the phone, because every time I actually answer the phone for that number I get bombarded with sales calls which all begin about 45 minutes after I pick up.

2006-08-22 21:59:57 UTCChris

Answered phone and got nothing but static. Said "Hello" a few times and the static got more intense.

2006-08-22 20:50:14 UTCCarol Sanders

They've called several times a day for the last few weeks, I finally Google'd them.

2006-08-21 18:35:48 UTCBekah

They called my cell phone and a partial voice message was left... it's automated so i guess the recording began to play when my voice mail picked up the call. i don't answer calls i don't recognize... especially on my cell phone!

2006-08-20 21:21:50 UTCJMH

They call every morning (including weekends) @ 8:30, leave no message and when you call the number back, it rings several times then answers to dead air

2006-08-19 21:43:49 UTCJT

Calling daily - no message. When I call back the line answers but nobody is there.

2006-08-19 13:59:00 UTCLaurie

They called and as soon as I answered, they hung up. I'm tired of this.

2006-08-17 20:03:05 UTCSteph

They've been calling like twice a day but not leaving a message. The happen to call when I could answer and it was DirecTV.

2006-08-17 05:26:05 UTCBridget

2006-08-16 23:22:31 UTCCarlos

i love how when you call the # back it hangs up on you. fantastic.

2006-08-16 17:56:50 UTCAD

2006-08-16 13:10:37 UTCLynne

2006-08-15 21:51:05 UTCCyn

2006-08-14 13:54:54 UTCNIKKI

They call and do not leave a message, then when I call from another number they hang up

2006-08-01 15:06:18 UTCJohnny

I've received repeted calls from this number.

2006-07-20 11:26:16 UTCDenise

They have wrong number but still calls EVERYDAY


How do I stop them from calling?

  1. Ask the unwanted caller to stop calling and put you on their do not call list (they are legally required to comply).
  2. If your number is registered with the National Do Not Call Registry you can file a complaint with the FTC.
  3. Block them with a call blocker:
