I won a Xbox Gift Card $5 from a sale in the Xbox One store, but cant use it.

I won 5 Us dollars instead and I cant use it so its just sitting in my Account also i won the code from the Messages tab

(New Messages from Xbox Live) is there a way that someone from the Xbox Team to take away the $5 US and give me the Roblox Premium(450 Robux/month) for 1 month as i wanted to buy it with that, or change the currency to SG Dollars which i checked is $7.20(Checked
from the Roblox App that i downloaded by Microsoft Store on my PC)

I screenshotted the proof

Unfortunately, it's not possible to change currencies to buy on the store. Did you win the gift card on the US store or Singapore one?

Thats because you cant use currency cards

You need to buy ms store GIFT CARDs which are meant for ms store

Not xbox store

Ms rewards doesnts pay out ms store gift cards

Xbox store and ms store are conpletely different divisions

wtf microsoft, i have to wait 2-5 months after the game i want goes off sale, just because someone at the store fed up my xbox card? you should work on getting it to where people can just ask you to change the card from a membership to a gift card. im going
to ps this is bulls_hit!

So, you just restated my problem as the solution. Awesome. I don't know anyone with a 360, and do not have a credit card. I can use my microsoft account balance drafted from the gift card to purchase things from the microsoft store, but not the xbox store
on the xbox website, even though it is an xbox gift card, and not a "microsoft store" gift card.
