I think Xfinity is scamming customers with the promise of free gift cards.

I was supposed to receive a $300.00 gift card for each of the 2 phones I got through Xfinity when I signed up for phone service. I was told THEY would be mailed out after 30 days of service. I've waited so long that the phone plan I picked for the phones has already expired. I've called, chatted with on the app., and gone to the local Xfinity store multiple times. They all said they were sorry for the delay but they were being sent right then. Still no cards. Am I ever going to get the 2 $300.00 cards? Or, was the promise of the gift cards just a scam to get people to switch to Xfinity Mobile? To me it sure looks like a scam.
