How to close Close Account- Impossible

OK trying to pay balance and close account

So I wait till the close of the settlement period 7 May 2023 - 21 May 2023. Button appears and made payment

Made payment on the account balance page twice card declined. After checking with my bank amazon charged a card that has not been used in a couple of years and was not my default card to begin with.

No Problem on may 5th settlement Amazon charged me $500 on my default card.

Re-saved my default card and made payment but but still in pending after 3 hours where as old card was declined in minutes.

So I wake up this morning with $147 charged to my account

Repeated requests to close account are ignored. So getting runaround when I open several cases they tell me to use account tool https://sellercentral.amazon.co.uk/help/hub/solution/DA_CloseAccount2

Of course can not close because of balance which was paid but still blocked from closing and only incurring new charges.

Closed all my listings 4 months ago and am in Vacation/Holiday mode

Really would like to just get this account closed.

Any Ideas here would be appreciated
