1. If you have any questions about your consumption records, you can call the bank's hotline in time. Submit disputed account information to the bank and consult suspicious consumption records.

2. The bank will ask the cardholder to provide relevant transaction information. At this time, the proof of credit card consumption is a good evidence.

3. If you lose the proof of consumption, you can also apply to the bank. At this time, the bank may charge a part of the inquiry fee.

4. In the process of inquiring about the disputed account, you may be worried about whether the disputed transaction will generate interest charges. Under normal circumstances, the transactions that are questioned during the inquiry period will be treated specially and no interest will be charged. Once the transaction is found out, if the credit card is indeed forged, or the account is wrong due to the negligence of the special merchant or bank operation, then you don't have to bear the transaction and return the relevant funds to the card. However, once it is determined to be a normal transaction, the bank will charge the corresponding overdraft interest, late payment fees and other fees.
