If there is an abnormal transaction in the account, it is a case of theft and fraud, and this bank will have a special department to deal with it. If you are not satisfied with the processing results, or fail to meet the previous expectations, you can explain to the bank again. If the bank still can't give you a satisfactory answer, you can directly call the Consumer Association at 3 15 to report the complaint, or, more simply, directly call the customer service phone of the China Banking Regulatory Commission to report the rights protection. Unless the bank can't handle it or doesn't handle it for you, you can ask the CBRC. Hope to adopt.
