I receive approximately 6-7 calls a day, starting at 8 am to sometimes 9:00 pm.  When i return the call i receive a recording that it is not in service.

Just received a call from this number at 12 pm. I believe it was the same number that called me yesterday too, except yesterday the call was from a private number. Yesterday, the guy would not hang up when I told him that I didn't know what he was talking about or that I wasn't interested. He insisted on going on about money, how I might be able to win $5.5 million or a Mercedes-Benz. I told him to stop calling me but he was giving me an attitude, and eventually I hung up.
