This is a user only forum. There are no Meta staff, no Meta moderators or community managers here. We cannot help with individual payment problems as we have no access to accounts. You will need to contact Meta official support directly. Here is a link to various ways to contact Meta.

Hi ​@Dook12 🙂

Have you tried adding the credit card on the web page, instead of the app?

https://accountscenter.meta.com/meta_pay_wallet/

This will not help with the store error, though… as ​@Maccyb123 said, you need to contact Meta support.

Follow the link he provided, scroll down to “orders and returns”, type “can’t purchase games” in the box and wait for the AI reply, then scroll down and click on “no, this did not resolve my issue”, next select Quest in the product box.

You’ll now get the option to contact support via email, chat or WhatsApp.
