I keep getting calls from them too!!! I finally answered, after their thousandth call, but they just hung up. This is some serious bull and I'm tempted to go postal on them.
I recieved a call this afternoon, and wondered..."Who is this?" So, I googled and this is what I found.. ay ay ay.. I did not return the call after seeing what type of thing it is suspected to be.
I got this call this morning. They asked for a Mr (my last name) and I told her there is no mr. As for the donotcall.gov list, I am on that for 2 years and the world still calls. I am guessing that if you start a business you can declare yourself non profit. Those are the only people not allowed to call.
