When I was applying for the developer app, we were being told to pay the usual $99 USD for the annual fee, but since the site process is a little long from Apple's end they suggested we use the app. Omn using the app the fee was added by $20 USD, is this normal?

Hello Apple Developer Community, I am encountering an issue while trying to pay the $119.99 Apple Developer Program fee through the Apple Developer app. I have linked a prepaid card to my Apple ID, which works perfectly fine for other purchases and subscriptions, but I am unable to complete the payment for the developer fee. Here are the details of the issue: Payment Method: Prepaid card connected to my Apple ID. Amount: $119.99 (Apple Developer Program fee). Location: Cameroon. Other Transactions: All other purchases and subscriptions using the same prepaid card have been processed successfully without any issues. When I attempt to pay for the developer fee, the payment doesn’t go through, and I receive an error message (Payment Failed). I’ve verified that my card has sufficient funds and that the information is correctly entered in my Apple ID account settings. Has anyone else faced a similar issue, particularly with prepaid cards or payments in Cameroon? Any advice or guidance on how to resolve this problem would be greatly appreciated. Thanks in advance for your help!
