The bank sent me a message to withdraw cash. I didn't withdraw money, so it was stuck with me. What happened?

Your card may have been stolen, so you should use the fastest speed to swipe your card or withdraw some money from any bank online store or storefront with pos machines to prove that your card is in your hand, so that if your money is lost, the bank will be responsible for compensating you. If you can't prove that you have your card, the money you lost is probably wasted.
