How do I cancel my Apple credit card

Hi , this is from Apple’s website

How to close your account

To close your Apple Card account, you need to contact an Apple Card Specialist:

1. Open Wallet on your iPhone and tap Apple Card.
2. Tap the more button .
3. Then tap the Message button to start chatting with an Apple Card Specialist.

If you want to open an account with Apple Card after closing one, you need to apply again. If you close your account and have an outstanding balance, you need to pay off that balance before you can apply for Apple Card again.
