New Seller card verification

Hi,

I apologise if this isn’t the right place to post or if this query has already been mentioned here but I’ve struggled to find any real advice.

I have set up my amazon seller as a business account (yes, bad advice from Youtube) my full ID, business details and bank account have been fully verified. My card has also had verification charges taken out and I received an email to say it’s verified and I can now sell on Amazon. Amazon shows my account as valid and the UK market as ready to list (I have put the other European countries on holiday.) I also have received multiple emails to confirm my account and card are now verified and I am able to sell. However, when I go to list a product, it gives me a message that my card is invalid or currently being verified.

This has been happening for the past 2 weeks. My bank account and card are with a high street bank in my personal name (the account I was going to use is an online bank and not supported so I’ll have to open another one shortly.) and all addresses for the business and my home address are the same and match my business details. I have an open case with Amazon but am losing faith that this will ever be sorted. Has anyone come across this is the past? I have no alerts stating I need to provide information and only get the card verification or invalid card message when I try to list a product. My card and bank however both show active and verified? Is there something I’m missing or doing wrong?
Thanks in advance
