Buy a game by mistake, how to refund?

Sorry to hear it. You'll need to call phone support to request a refund. Click this link to get the number for your region http://bit.ly/2ee23wg

You said you'll buy it on the xbox? you want a refund to buy it again? or was some grammar mistake?

In-game items or codes once consumed can't be refunded

You buy an in-game item it's consumed immediately

If you didn't receive it you need to talk to the developer

Fyi if it's a Diablo 4 items read the description it explains how to access it

Diablo 4 items are connected to your battlenet account NOT ms account not sharable

Abusing the refund policy is never a good idea

That's how people GeT temporary suspended for marketplace theft fyi

It's not try before you buy

It's for.legitimate mistakes

You can check your account.Microsoft.com to see how many refunds you ordered

Now If you mean how many refunds can you get?

I wouldn't ask that

You have to keep in mind it's not try before you buy and if you are right abusing it you could face marketplace suspension as it's meant for legitimate mistakes not I beat It as fast as I could now onto the next game

How would I get out to Xbox Support when it was them that made the mistake. I asked for the refund, then after realised that I wanted the game. So i asked them to stop the refund, they would still do the refund.
