Having issues with my payment

Most roads lead to contacting your card issuer or check if you have a pending charge that has not been paid.

If your payment method is declined in the App Store or iTunes Store - Apple Support

You may need to add a different payment method. If that card had previously failed to process a charge, Apple may have determined it to no longer be a valid payment method. Also if you requested a chargeback from your bank for a previous charge, Apple may no longer user it as that is usually done for a fraudulent purchase. While Apple would not know the reason for a bank declining a transaction, you can contact them here:

Then that sounds like it is not going through the Apple Account where it is managed by Apple. Coins can be purchased either with your Apple Account where it is managed by Apple or directly through TikTok. Otherwise the purchase in the TikTok Store or Ad Space can use the payment method added to your TikTok account where it is not being processed by Apple.

The only recommendations on your device to try is to remove the TikTok app and install it again to clear any caches or remove any VPN if you have one installed. Beyond that, not sure why TikTok would be telling you to contact Apple if they are the ones attempting to process the charge.

• Are you using the in-app purchase method where you double click the side button, followed by Touch ID to authorize the charge?
• Did you enter your card details on TikTok manually, or use Apple Pay?
• Is it for a purchase of Ad services where you choose the payment method on the TikTok app?
• Are you unable to make any other in-app purchases using your Apple Account?

Verify your billing method and type on TikTok Ad Manger:

For a problem with your payment method on your Apple Account, review the information provided in the first post. There is also a link to contact Apple directly, although if the bank of the card used for your Apple Account declined the charge, Apple will not be given the reason. In that case you would be directed to contact the financial institution or add a different card to your Apple Account.
