when i want to download a new key, I get this error: An unexpected error occurred. Please try again. If the problem persists, please contact Apple Developer Program Support. https://developer.apple.com/support

Hi, this is very urgent. ive purchased the apple developer program a few days ago from the developer app, and it all went smoothly, and the money is gone from the bank. I've also received the invoice and agreements in the email. but now, it says in the app that account enrollment couldn't be made from the app for this Apple ID. also when signing from the web it says that I need to complete the purchase and leads me to buy it again. please respond fast thank you, the money is already paid.
