Hi siyady89,
Thank you for posting in Apple Support Communities. We see there is a problem with your payment method.
According to If your payment method is declined in the App Store or iTunes Store
"If a payment method can’t be charged
- Use your device to check your payment information. You might see red text that explains why the payment method can't be charged.

- If your card was declined, add a new payment method or update your payment information. You can add multiple payment methods to your Apple ID.
- Your payment method will be charged for the unpaid balance. Then you can make other purchases and update your apps, including free apps.
If you use Family Sharing and Purchase Sharing is turned on, the family organizer must update their billing information or add a new payment method. If you're not the family organizer, you can't change the payment method."
Cheers!
