why i cant complete my payment ?

Hi ahmey208,

Welcome to Apple Support Communities. I see that you're unable to complete a transaction under your Apple ID account. I can help provide you additional information.

There are a couple of reasons of why a payment cannot be completed. I recommend to review the details in this helpful article: If your payment method is declined in the App Store or iTunes Store

For additional assistance, I suggest contacting Apple Support through this link here: Contact Apple Support

Cheers!
