i just received a call from this numbar

i received a call from this number said "you've been removed"

Rec'd call, did not answer, no message left.

Rec'd call. It said it was not a sale call blah..blah...then he said he something about hip replacement. I hate this time of calls. Does anyone know if we get charged when we answer it?

received a call from this number even though I am on the do not call list.
