Credit cards can be cancelled by phone or by outlets, and different cancellation methods have different requirements for regions. There are many regional differences, and it is impossible to verify the original information. This is why banks have to cancel their card outlets even if they have achieved national networking. There are no regional restrictions on canceling calls. You can call customer service directly to contact the bank to cancel, and you don't need to go to the card office to cancel.
When canceling the credit card, it should be noted that the credit card can only be cancelled if there is no debt and no balance, and there is a waiting period of 45 days when canceling. There is no charge for credit card cancellation, and there will be no bank for other credit cards. After the card is cancelled, the supplementary card will also be cancelled. After successfully canceling the card, cut the card and handle it properly.
