Two calls today and one yesterday. Never leaves a message. I filed another complaint to I do this every time they call. Maybe someone at the FTC will get a clue with all of the complaints I am filing. Hopefully others are filing complaints also. These telemarkerters are the ones that should be at Guantananmo Bay along with the Taliban.

A google search reveals this to be an especially obnoxious telemarketer of home security systems.

Maximum Security
770 Alcantar Cir
Sacramento, CA 95834

Most of their reviews in CitySearch are from people they have pissed off by calling too much. also has numerous complaints about similar calls from a variety of numbers/locations

A typical quote:

Never said his name. This was a robotic voice that said something about wanting to place a home security device in my home. I hung up. I then reported this number to the FTC complaint site I also called the number back and received an all lines are busy message. I am on the Do Not Call List, and have been for over 6 years.

For those who keep getting calls from this number and you want it to stop. Just call back and fallow the instructions and you will be placed on this company's do not call list.

I have been getting these calls two to three times a day.
When I don't answer there is never a message. I have answered twice while busy and forgot to look at who was calling first and there is no one there. I am also on the do not call list. This is really frustrating.

I received at least 3 of these calls a day on my cell phone. I typically don't answer calls that I don't recognize. This time I finally answered. He said "this is Tom from Home Protection and we're looking for homes in your area to showcase." I told him my number is on the national do not call list and asked how he got my number, dead silence.... I told him, "don't call again" and he hung up.

I've received half a dozen calls from this number over the past couple weeks; two so far today. The first time I picked up and heard a recorded message so I hung up. My number is on the do-not-call list so I'm off to file a complaint

The SOB telemarketer wanted to sell me a home security system. While I asked to be placed on their do not call list the SOB just kept on talking over me with his canned speil. I filed a complaint with the Federal Trade Commission through their do not call web site.

Received a call from this number. No name came up on caller ID. Called the number back and it went straight to a fast busy signal. A couple hours later I receive a call from this number again. I answered the call but put my phone on mute. A few seconds later a man said "hello?". I stayed quiet to see if he would hang up. He continued on, 'this is Tom with home security systmes. Would you like a free security system installed in your home for putting a sign in your yard?' I kept quiet and the guy hung up.

I don't answer calls from numbers I don't recognize. Especially if I have never seen that area code before. They didn't leave a message and when I tried to call back I got a message that all circuits were busy.
