Xfinity Mobile Gift Card Scam Attempt

I know most of you know this but yesterday I received a call saying if its been two weeks and I haven't received my Xfinity Gift Cards please call this number.  I know its not from Xfinity but I wonder how any scammer knows I am waiting on Xfinity Gift Cards.

Get many calls claiming to be from Xfinity:
