This call iss very annoying and uses minutes as I answer my calls

I just got a call from this number on 12-28-12.  They called earlier and left no message.  This time I answered.  And I was told by someone with a foreign accent that I was selected to win a Walmart gift card.  When I asked to remove my name from their calling list and not to call back again, I was cut off or the person hung up - idk which.

Called 3 different times in a hour. Ignored them. They left no message.

save your minutes. Kept getting calls On my cell. I saved the number and named the contact: "Mystry Caller"

Whenever that caller calls me, (and it been 5 times today since 11am ) the name comes up, I igore it.

I looked it up on Google and  found this forum.

Keep getting calls on my cell from this number all day every hours.  Thanks to my Galaxy III I was able to place this in my reject call list, that takes it striaght to voice mail. Caller nevers leaves a message.
