Problem verifying Debit Card on Seller Central

Hello all,

I have been having receiving the below message for a month now:

‘Credit Card Invalid
You must update your existing credit card information or add a new credit card to regain full access to this seller account.’

I used the same Debit Card to open and activate my account months ago, so I do not know why it has suddenly ‘locked’ me out. I have verified this card multiple times but nothing changes.

Anyone else experiencing this?

Thanks.
