1. This situation may be due to the failure maintenance of the banking system, the overdue freezing of credit cards, the locking of bank card passwords, etc. You can call the bank's credit card customer service hotline for consultation.
2. Please contact the bank in time in case of any abnormality. Notify the bank immediately of repeated deductions. Due to some customers' weak awareness of the safe use of credit cards, coupled with the increasing variety of criminal means of credit cards, disputes caused by stolen credit cards and irregular operation of merchants have gradually increased.
3. Personal information must be protected. Of course, cardholders should also be vigilant. In order to prevent credit card risks, people should go directly to the banking institutions to apply for credit cards, and do not entrust multiple channels to prevent transaction risks. For banks, credit card issuers are constantly upgrading and improving credit card security measures.
5. Compensation for loss reporting ensures the rights and interests of customers. In fact, even if there are abnormal situations such as merchant's wrong deduction and illegal misappropriation, cardholders don't have to be too anxious. As long as they cooperate with the bank or the police to investigate and collect evidence, they can generally solve it smoothly. If you find that your bank card is lost, you can greatly reduce the risk of misappropriation of funds as long as you contact the bank to report the loss immediately. Entrust others or an intermediary to handle credit cards.
