first, call to control your card and explain the situation, so that even after the repayment, the card can't be used in the networked credit card machine and ATM machine. For insurance, please ask the bank to temporarily reduce your credit limit to (usually up to 3 months), and you can resume it when things are settled (note that it is a temporary adjustment, and if you want to resume it permanently, you will have to re-examine it later)

Or you can. But don't lie to the bank if any card is lost or stolen. Because to withdraw cash, you must have a password. You even told your friends the password! The bank will not believe it. Moreover, the bank can access the purchase order and the cash withdrawal video, and you will know the truth when you check it.

when you apply for a card, there will be an agreement on the application form of all banks. One of them is that the credit card you apply for can only be used by yourself (including family members). If you lend it to others, all risks and losses will be borne by the cardholder.

according to the above article, if you can't find your friend and can't repay, you can only repay the consumption money yourself first, and the bank won't care whether you lend it to others.

finally, settle the economic dispute with your friends. Try to communicate with your friends and explain the situation. If a friend really has practical difficulties, then help if you can. If you are careless, please don't hesitate to call the police directly. You can ask the police to contact the bank for assistance.
