I have been locked out of my seller account for 3 days and repeatedly told my change method wasn't valid even though I hadn't touched it and it had always worked.

Just over a week ago i deleted an expired personal card from my Prime account, i did not alter my charge method for my seller account. My charge method maintained 'active' status throughout.

I have fixed this without help or assistance from amazon.

For future reference for this 'system glitch' this is how i fixed it;

Delete all payment methods from Prime account, add relavent cards back to Prime account and verify from there.

Delete charge method from seller account.

add charge method already verified in Prime account.

Problem instantly solved.

Amazon's card verification process does not work from inside the seller account using the button provided, the card has to be verified from the shopping Prime account first.
