I get that same exact call as everyone else..... I have a theory but could be wrong. I have Tmobile and I had recently called them about my bill. Funny thing is, at the end of the call the lady asks me if I want to add a new thing to my plan that stops unwanted phone calls. So personally I think its a scam so that you add that thing to your plan and pay the company more money. Does anyone else with this problem have Tmobile??
