But you can't refuse to pay back, because not paying back will generate interest, and it is a high interest rate.

You should raise an objection to the bank, claiming that the money was not consumed by you, and it was an accounting error. The bank will check, and if it is confirmed that you did not pay, the money will be returned to you. Some banks will refund the money to you as long as you raise an objection, and at the same time carry out verification work. If the verification proves that you are wrong, you will deduct the money and charge your inquiry fee (for example, China Bank Charge 15 yuan); If the verification proves that you are right, then

no problem
