Microsoft rewards xbox gift card wrong currency?

I redeemed an Xbox gift card through Microsoft rewards for $5, as there was no option for a gift card in British Pounds, and i thought the currency would simply convert to GBP after entering my account. It didn't, and I now have $5 in my Microsoft balance
that i can't use to purchase anything. Is there any way to convert it to GBP, or at least receive a refund on my Microsoft rewards points?

If you redeem your Microsoft Rewards points for a $5 Xbox Gift card. You receive $5 on your Microsoft account. You do not receive a physical gift card.

 

You could try contacting support and speak to billing, but generally they can't exchange currencies. Contact Us | Xbox Support

Otherwise, you'd want to try contacting Microsoft Rewards customer support to see if they can refund the points and
figure out what happened so it doesn't happen in the future.
