A SCAM - and when you call the number back on another phone and block your number, a recording says if you believe you received a call by error, press 5 to be added to our do not call list.......and how is this supposed to happen if you blocked your number, they don't really remove you to begin with.
They have called three days in a row after I asked them to remove my number from their list. One more time and I will try to report them. As I understand it, they can be charged 500.00 per call after you ask to be removed.
