This phone number calls me every.single.day!!!! When I answer they immediately hang up. When I called back I m on hold forever. I hate wasting my time. I was able to get through once to a representative and it turned out to be for someone who was not me. I advised them of that and they agreed to remove my name off their call record. That was three months ago. The calls come in every day....STILL!!!
