first time call from this number, but no message left. Wondering who it is!

Received numerous calls from this number..shows up on the caller i.d. as British Columbia.  I've never answered it.

Can we get a "do not call list" for cell phone?

Some vacation package to Las Vegas

i get a call from this number more than once a day.  i never answer it, because i don't know who it is.  don't they get it that i don't want to talk to them?!?!
