This number started calling me yesterday. Once in the morning and the other at night, my husband pick it up the second time with no answer and hang up. I answered the call today and the guy came on the line and said "thank you for calling (didn't catch the name) my I help you" so I just hung up.
Could be one of these places that calls, hangs up just to test your curiosity on who it might be. And when you call it back you get next months phone bill and there is a $10,000 charge on the bill just from calling that number. . . .
