I did a white pages lookup on the address, which also included a google map option. The location is a dirt road in the middle of a cross between an industrial park and a suburban housing development. I have reported them to the donotcall registry and the BBB of Iowa.

I received calls from this # saying they had personal business of a serious nature. They were very rude and would not divulge ANY info about themselves unless I had given them personal info. I refused, which made the woman even more rude.
Supposedly they were affiliated with Verizon and had my phone info on file. I called Verizon directly from my bill, and had them call the number. The rep told me it was most likely a scam.
Further research yielded they are scammers and debt collectors out of Des Moines, Iowa. They have over 40 numbers from Iowa, Missouri, etc..
If you want to report them, here is their address: CBE Group, 1031 Office Park Rd., West Des Moines, IA 50265 Phone # 515-226-0218.

I received these calls saying there was a change in my account, and I had to contact Verizon within 24 hrs. The message said to enter my phone #. I called Verizon from the customer service # on my bill to verify. The Verizon rep put me on hold and called some of the numbers. and got back with me saying they were all most likely a scam.
It is one of three numbers I have been receiving calls from. The other numbers were: (Des Moines, IA) 515-344-3550, (bill collectors and they were particularly rude), and (Columbus, OH) 614-360-9213. Verizon might have given/sold personal info to these scammers. Beware. When in doubt, call the number on your bill, NOT one of these numbers. Deal with Verizon directly, that's why they have cust service!
