So unused cards must be cancelled.
Credit card cancellation is not allowed at the counter.
You must call the credit card center to cancel the card manually.
However, it is impossible to directly transfer the labor force without opening the card.
I'll teach you a method. After the phone call, select the report loss option.
This is not for you to report the loss, but for you to consult the manual without opening a card.
After entering the workforce, you can ask the customer service representative to cancel the card.
good luck
