Amazon Keeps Rejecting My Credit Card Payment

I am trying to purchase a WMF pressure cooker through the Amazon mobile app, but since yesterday, I have repeatedly received a “payment cannot be verified” error at the payment stage and have been unable to complete my order. Every time I try to pay with the same credit card, the system rejects the payment, preventing me from placing my order. This issue occurs every time I try, and there is no clear information about whether the problem is with my card or Amazon’s payment system. I contacted customer service, but they were unable to provide any solution to the payment issue, and the problem is still unresolved. I want to purchase the WMF pressure cooker without any problems and have my payment successfully approved by the system. I am requesting that this recurring payment verification issue be investigated and resolved as soon as possible.
