Card Verification

Hi, I have recently set up a business to sell on Amazon. I have provided all necessary documents and my card details are recorded on my account. But I cannot list products and receive the error message as below…

Problem with your Seller Account

“You’re currently unable to add or edit listings because either the credit card on file is invalid or the credit card is in the process of validating, which could take up to 24 hours. Please ensure that you have a valid credit card uploaded in Account Settings.You’re currently unable to add or edit listings because either the credit card on file is invalid or the credit card is in the process of validating, which could take up to 24 hours.

I have been waiting for a number of days and keep getting the same error. When I look at my account settings it says there the card is verified?
