You mistakenly deposited money into a Bank of Communications credit card. You want to know how to withdraw it or transfer it to another Bank of Communications or debit card of your own. The first question is whether you have any outstanding balance on your credit card at Bank of Communications. If not, you can withdraw money from an ATM, but there will be a handling fee. If you owe money on your credit card, you cannot withdraw it after you have deposited it in it.
