Payment mode Credit card not working for my iTunes

Hello kelfest,

Thanks for participating in the Apple Support Communities.

Check out the information below to see if that helps to clear up what you're experiencing. You can also locate additional information here: If your payment method is declined in the App Store or iTunes Store - Apple Support

If a payment method can’t be charged

1. Use your device to check your payment information. You might see red text that explains why the payment method can't be charged.

2. 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.

3. 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.

See which payment methods are accepted in your country or region.

If you haven't tried adding a new payment method to your Apple ID, let us know if that helps or not. If you're still unable to utilize a new payment method, Contact Apple Support so they can check into this with you in detail.

Have a great day!
