Xfinity Visa gift card expired - unused

I received $200 gift card for using iOS BYOD devices with Xfinity mobile. Yesterday I thought of using and activated by dialing the number on the card. It activated my card but also told me that current balance is zero on my card. When I checked my card, it was already expired on 03/20. I didn't get chance to use a single dollar from the gift card. I never expected a gift card with very short validity.

Can I get a replacement card?

Thanks.
