I have been having this problem too. I looked up the area code and it was from a few places in MO. I had this problem Befor with another number and it turned out they were some collage that got my cell number. Hope this helps.

these people constantly call my phone i keep telling them its a minute phone but they still call about 7-10 times a day!!

This [***] keeps callin an hangin up on me even after I requested to b off his call list he's called 13 times already today

I have gotten a total of 12 calls between today and yesterday.  They ask for someone other than me.  I told them wrong number.. I have registered twice for do not call list.  Spoke to someone two times, both times they hang up on me when I'm telling them they don't need to call me anymore... GRRR!! One of the Reps tried to tell me they got my number from a recent purchase, hmmm how vague??

I'm getting 4 - 6 calls a day.  I answered once, but when no one responded, I stopped.  Still getting the calls.
