I received a debit message in the supermarket.

It is possible that the banking system abnormally triggered the short message port to be issued many times. Check the transaction details. If there is no problem, don't pay attention to it. If you only charged once but deducted four times, please immediately call the customer service of the issuing bank on the back of the credit card to report the loss of the credit card and explain the specific situation to the customer service! Then please call the police immediately.
