1. Since you didn't open it, it was inexplicably opened. First of all, you should ask ICBC not to keep the customer's credit card secret, because credit cards are usually opened by phone with the user's ID card and the number on the card, which means that your information may be leaked. Why do you want to find ICBC for such a ridiculous thing?
After reading your question, I can see that you don't seem to need the overdraft function of this credit card, but you just think that the appearance of the card itself is beautiful. If yes, please bring your ID card to return the card. It seems that among all banks, ICBC is the most troublesome, and it needs to bring proof to the bank counter to cancel the card. Other banks just need to call. On the one hand, it will be safer to cancel unused cards (in fact, you can cancel them when you run out). Secondly, there will be no other fees such as annual fees.
3. Call ICBC Credit Card Center and tell them that your card is ready to be cancelled. You have lost confidence in ICBC. As for the cost, it's not your fault. If they are willing to offset the annual fee, you can consider continuing to use it (remember, all annual fee-free credit cards are generally deducted first and then returned, but you must save money after applying for annual fee-free successfully, otherwise it will be cancelled)
4. Call the Consumer Association
