Why is 80 yuan missing from my postal account for no reason?

You can say these two situations:

1. Did you add the annual SMS service when you opened the account? This service is that when the account balance changes, the postal short message platform sends a short message to your mobile phone in time to inform you of the change of the account balance. The annual fee of 30 yuan will be deducted from your account at one time.

Your brother's remittance may be cross-border and urban, but your brother didn't give you the transfer fee. Because the transfer of postal currency cards across regions and cities requires handling fees, the charging standards are: deposit and withdrawal in different places in the same city in this province, and there is no handling fee for transfer; 0.5% handling fee is charged for cross-border and urban areas in the province, with the lowest 1 yuan, the highest deposit in 20 yuan and the highest withdrawal and transfer in 50 yuan; A handling fee of 0.5% is charged across provinces, with the highest deposit in 20 yuan, the lowest withdrawal and transfer in 2 yuan and the highest in 50 yuan.

Then, your 80 yuan money may have been deducted from these two accounts, one is to send a text message to 30 yuan during the year, and the other is the remittance fee 1 10,000 yuan.

If these two possibilities are not saved, you can go to the place where you open an account (or any branch in the province where you open an account) and print a detailed account to see how it is deducted.
