Why didn't CCB inform you of the cancellation of its credit card?

I canceled, too. I forgot if I got the message.

However, whether you receive this message will not affect your credit card cancellation. Even if the SMS is sent to you, it just tells you that a card has been cancelled, and you don't need to confirm the cancellation by SMS.

There is nothing to entangle in this matter.

As long as the customer service on the phone tells you that the operation has been successful for you, it is ok, and then you cut the card and destroy it yourself. It seems that you have to wait 45 days to find out the accounting situation, and then if the funds have not changed, they will be officially cancelled.
