What's wrong with the SMS notification bill of the Postal Savings Bank?

The detailed description is as follows:

If the bill notified by the bank SMS is different from your own calculation, it is suggested to print the running water at the bank first, and then check it one by one to confirm whether the bank really made a mistake. If yes, you can submit evidence and then apply to the bank for verification. If verified, you can ask the bank to make up for the loss.

Of course, under normal circumstances, the probability of bank mistakes is still relatively low, so when submitting an application to the bank, it is recommended to check carefully first to see if you have missed some money.
