Card charged yet amazon says it can’t be charged?

Amazon tell me this on the charging methods page:

Unable to charge We are not able to charge your account. Assign a valid charge method to restore full access to your seller account. For more information, refer to our Help Pages.

I then get charged 39 British pounds!

Then when entering amazon seller Iam greeted with this message:

Invalid Charge Method You must update your existing credit card information or add a new credit card to regain full access to this seller account. View Charge Method

And the charging methods still displays the same message as mentioned before.

Their customer support is useless and now Iam here. Any help?
