Xfinity Promo Gift Card

Well... this forums site is slow and keeps kicking me out when I selects tags so imma just put that this promo gift card for being active duty military is dog shit and I can't use it anywhere. Fast food, online, POS, Amazon, or even tap to pay, even though it says "anywhere that master cardbis accepted". Give me a damn break. I can't use this card anywhere. It's "active" according to when I call, but I still can't use it after all the "support tickets" they say are submitted for me. Never should've depended on such a lousy program. I'd rather keep my military service to myself and spend my days not worrying about whether or not I can pay for something without Xfinity.
