Design lab payment

You'll need to contact Microsoft Store support for assistance. https://support.microsoft.com/help/28808/microsoft-store-contact-support

It depends on whether you are talking about a normal controller from the Microsoft Store or a Design Lab one (as noted "theyre more expensive on amazon then a custom designed one"

Normal controllers bought through the Store can use MS credit. Design Labs controllers do not allow use of MS balance of gift card to purchase:

"No, there isn't a way to use gift cards, codes, or CSV to purchase a controller.

You also can't make split payments between account funds, codes, and another payment method on file with your Microsoft account."

Xbox Design Lab FAQs

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello Fr0zenIc3, unfortunately Microsoft has not published any official statement, but since the Design Lab store was redesigned the system has not accepted more credits for the payment of the controls.

So we can't speculate whether it's temporary or definitive in the Design Lab payment system.

After you add the gift card to your account it's added as your Microsoft account balance. Choose that payment option when making your purchase from design lab.

I take it you are trying to use the Xbox Design Lab? Try to contact support and say you're having trouble with the controller design lab. Or see if there is a support page/email/number on the controller design lab website.
