These guys call once or twice every few months. I've talked to them and told them over and over not to call. I asked them whether or not they knew about the "Do Not Call" list. They do, but they think they can call anyway. Anyway, I report them to www.donotcall.gov every single time they call, but nothing ever gets done. Lots of good that law did if the government isn't going to enforce it!
I think the numbers
205-815-8953
205-815-8956
205-815-5653
etc., all come from the same source.
205-815-8953 has called my home this morning around 9 AM.
I cannot confirm that what they are doing is illegal, but I can guarantee you that I have never had any type of business relationship with these people. Don't know how they got my number; only going to assume that their randomly dialling or picking a number out of a phone book...
I'll be sure to record the phone conversation and submit it to the appropriate authorities next time they call me :-)
