I am writing to urgently request your assistance in resolving a persistent issue with validating my credit card on the Amazon Seller platform. This problem has been ongoing for several months, causing significant disruption to my ability to manage my seller account effectively.

Despite multiple attempts to add various credit and debit cards to my account, I continue to receive error messages during the validation process. However, the system often indicates that the card information has been successfully added, only for errors to occur later.

This issue has severely impacted my ability to conduct business on Amazon, including listing new products, managing existing listings, and processing orders. I have thoroughly checked all card information for accuracy and ensured that the cards are valid and have sufficient funds.

I would be grateful for your immediate attention to this matter and a thorough investigation into why these validation errors are persisting. Please provide me with clear guidance on how to resolve this issue and successfully validate my credit card so that I can resume normal operations on my seller account.

Thank you for your prompt assistance in this urgent matter.
