Same here.  Received a call.  No message left.

Got a call from this number. No message left.

Called this number back and it turns out it's a telemarketing group claiming they give away $100 a day in gift cards and other prizes and that I was a "subscriber."  There is an easy option they give you to cancel your "subscription," which I did and they said it would take 7 days to be processed.  Hoping this means the calls will stop.  It was all voice mail--no human contact.

Don't know this number

Got a call from them. Wasn't able to to pick up. When I called back there was a voice message saying that my subsciption had been cancelled and my number removed from their database but they didn't say who they were. If it is a telemarketer than good riddance.
