Has your credit card been bound to other services besides ETC? For example: video membership, Amazon membership, etc. If so, then just turn off the automatic deduction function. So you first need to check the detailed bill of your credit card to see which merchant deducted the monthly deductions, and contact the merchant to cancel the monthly recurring deductions. If it is a toll, it may be delayed. Some banks' ETC tolls are not deducted on the same day, but may be settled once a month. So if it is a toll, you can also check the details through the official website or official account of the High Executive Administration.
