"This card has already been redeemed" error message

Hello, recently my Xbox gold ran out, I had a prepaid card for 12 months so I scratched it off and entered it in Xbox. The first time I entered it was in the actual store. It gave me a message like "an error has occurred please try again later." So then
I tried going to my subscriptions and redeeming it from there, to which I got the message "This card has already been redeemed" which it clearly hasn't. I checked the history of purchases and transactions and it never appeared. The weird thing about all of
this is that my gold said it expired today yesterday, for example:



This is what it looked like yesterday, on the 26th of June 2020.

I would appreciate if anyone could help out and tell me how I can actually redeem this card,

Thanks.

:)
