hello, how can i solve this problem?

This problem do you have in another type of acquisition, such as the console, or MIcrosoft page?

Best option would be to log into your
Microsoft Account page, and check under Payments & Billing > Payment Options and review that everything is in order for the listing there. You can then check the specifics and update if necessary, and if there is an issue, it should provide some more details
on that page what the problem with the payment option might be.

Hi TP2020,

Thanks for reaching out to the forums. From what I can find, this is possible due to a corrupted user profile. We recommend that you contact Microsoft Store Sales and Customer Support to get this resolved, we don't have access to your account info. You
will find the contact number based on your location
listed in here

You could also reach out to
Xbox Support by following the steps below:

• Step 1: Billing & Accounts
• Step 2: See other options
• Step 3: Payment & Billing
• Step 4: Show Contact Options > Chat with Xbox Support

I hope this helps.

Have you asked your financial institution or bank if they are blocking the charges?
