Got a call from(780) 809-0795 tonight. Who are these people?

I think it was Direct Buy  - another scam,  they want me to pay the markup on product up front and order trough them for all sorts of stuff.  Great idea? NO!  realize just how much money you have to spend to start to make a saving... I will stick with Costco, it is cheaper.  And my call display number was cc 18.  do I win anything?

Call display comes up as "CC 7". No message left on answering machine.

Got a call from this number twice in one day no message was left on the machine the first time, the second I answered and there was no one there, just silence. Number came up as CC 5

i got a guy calling me from this number saying is this _____ My name and said I won  50.000 home makeover I hung up I think it is a phone sacandle! c6

Got a call twice in 10 minutes from (780) 809-0795 cc 18, they hang up as soon as we go to answer. Don't know who they are.
