The Postal Savings Bank called and said that the credit card had been withdrawn.

Excuse me, do you want to ask, "Is it credible that the Postal Savings Bank called and said that the credit card was refunded?" This may not be credible.

If you receive such a call, it is really impossible to judge whether it is true or false customer service. You can hang up and check. You can also contact the customer service of the bank yourself or apply for cash withdrawal by credit card through official website Online Banking. Don't provide relevant information directly according to the requirements of the other party.
