Redeeming physical Microsoft retail gift cards

Hi everyone,

Just a little curious with the retail stores closing up, anyone encountered the same issue I have with redeeming the gift cards?

I have three $100 cards i received as a promo for buying a laptop with them 2 years ago. Still got the receipt and everything. Was wondering if anyone knows how to redeem it since those cards state retail store only, and does not have a 25 pin.

I've tried to patch to customer support, and so far have been transferred between 5 channels, all of which state a different department can help. I've also been call dropped twice (assuming the wait took too long and the call got dropped, 15 mins+ on hold
that time).

Any help would be appreciated!

Thanks everyone

:)
