What is the reason why I didn't notice the deduction when I got on the high-speed etc a month ago?

Reasons for not notifying the deduction for a long time include: 1. SMS reminder service is not enabled or the number of SMS notifications is less than this number; 2. The settlement time between the expressway and the bank is inconsistent, and the deduction is relatively lagging behind; 3. Unable to deduct fees due to system failure; 4. Being too close to the car, the system can't recognize it normally. Under normal circumstances, the expressway management department will submit the details of the previous day's fees to CCB every day, and CCB will deduct the fees according to the details on the same day (in case of holidays). If the deduction fails, a subsequent deduction will be made. Therefore, the date shown in CCB's bill may be inconsistent with the actual adoption date, which may usually be 1-2 days later. Sometimes it is still possible to buckle multiple strokes together.
