Medicare, somehow got ahold of user numbers from AT&T I know this being I have a family account with 4 lines, all four lines get calls saying you requested information about medicare and asked about 5 to 6 questions with a machine responding. once you finish the inquisition they place you on the phone with a call tank. opting out of the phone call is impossible, you press 1 and they still harras you with more phone calls. I wish I could reach through the phone with my 9mm and shoot them all.
