Account Suspended - Credit Card Invalid infinite loop

I recently created a new seller account in the hope of being able to sell on Amazon. Sadly once I was past the horrendous verification process my account was instantly suspended for having an Invalid Credit Card…

I instantly changed the credit card number for all stores to my Visa Debit to ensure it wouldn’t cause an issue and all test payments were taken successfully.

24 hours later I’m still no closer to having an account - under the account health menu option it takes me through a few steps before flagging the same Credit Card Invalid page. The only option I am able to type and send a message to get’s an auto response from Amazon saying this is the wrong email - none of the suggested links work and repeatedly send me to the page attached in my screenshot.

Does anyone have any help on how to get around this?
