A seller I bought a code from requested a charge back from their bank on a code they sold me.
What can I do about it to quickly resolve the issue?
I’ve contacted support and my Nintendo suspended my account because of it.
Hello,
You will have to wait for a reply from Support since you already contacted Support.

Might take a few days for a reply so best that you have included a detailed explaination and proof in the ticket you sent to Support.
For Nintendo, you will have to contact them directly to try to solve your suspension since they suspended your account.
