Ever few months or so I always get a call (well two back to back ones) from this number and others for the same two ladies. (Which I have gathered to be the same one from other types of callers). I really just want them to stop, it's getting annoying.

Called back and it was Pfizer Pfriends program.

Was a robo call and didn't identify themselves.   I hanged up on them.
