They are constantly calling my cell to the point of harassment.  They *never* leave a message.  I tried calling the number back and got a generic "the voicemail box has not been set up for this number".

I guess I will have to report them to my provider and have them blocked.  This is ridiculous.

File a complaint with the FTC against them (CBE Group Inc)  

They are in violation of MULTIPLE rules the Fair Debt Collect Practices.

The message I noted from you and one other person, is from the same number that is calling me. The difference is, they are calling no less than 6 times a day. When I call the number back, it is automated and requesting an account number. Who would be stupid enough to enter an account number when you don't even know who's calling. After Google-ing this I will continue to ignore this number. Eventually, maybe they will stop calling my number. This started the beginning of March and is still going on, so far today they've called 3 times, but, it's early. 8=)
