I signed up and entered my Apple ID. I completed the registration process and paid $99 through the enroll link. All steps are done correctly. And at the end, the message that the payment will be completed in the next 2 working days was displayed, and at the same time, an email was sent to me that I have to wait for 2 working days. But after several days, no email has been sent to me to complete the registration. And my registration is still pending. I would be grateful if my friends could guide me on what to do.
