Why does my bank card always deduct 3 yuan several times for no reason?

The money in the postal savings bank card is always deducted for no reason. The possible reason is to handle the SMS reminder service.

The specific process of canceling SMS reminder at the counter is as follows:

1. Copy the ID card with the assistance of the staff in the bank lobby and queue up at the same time;

2. Fill in a business application form, select "SMS reminder" in the column of business to be cancelled, and attach the mobile phone number bound to the original SMS reminder service;

3. When the number is called, hand over the bank card, original ID card, copy of ID card and business application form to the counter staff, and cancel the SMS reminder service.

If the bank card always deducts money inexplicably, you can take the bank card to the bank to check the daily account and ask the bank to cancel the automatic deduction project, and that's all.
