This number called my cell phone last night, I did not recognize it so I did not answer, however, just before the call I had another call from 801-736-4400 (which seems to be some sort of scam)...after the 405 call I got one that was "UNKNOWN", so by now I am curious so I answered, it was a scam that the woman was trying to say I won an online sweepstakes.  I did get a letter and check in the mail, and after my own investigation found out that it was all a scam and after contacting the company whose name was on the check found out that I was the 8th person to call them and that they did NOT have anything to do with it, it was a fraudulent check and they had turned it over to the FBI, so I filed my own complaint with CI3 and the FBI.  I told the woman who called with the "UNKNOWN" number that I had turned it over to the FBI and she promptly hung up and has not called again.  Thank God that I didn't deposit the check without doing some investigating of my own.  BEWARE!!!!
