Who called from 7082797640

Prize Distributors said he is calling because of my contest entry.  NEVER ENTERED!!  I am supposed to call him back to see what I won.

I have received a number of calls from this number.It registers as Prize Distributors. They hang up if I answer, otherwise the message states to call back.

Prize Distributors - called our office line and hung up. So I called them back (mostly to see who it was), and then hung up on them even harder. That's what's up.
