What should I do if my CMB credit card pre-authorization changes my consumption bill?

1. First check the signed order and confirm the transaction type.

2. Secondly, activate the SMS notification function to learn about consumption status at any time.

3. Then confirm that the merchant revokes the pre-authorization to eliminate risks and losses.

4. Finally, cancel the reservation in a timely manner, request the hotel or agency to handle the pre-authorization cancellation procedures, and ask for the cancellation number as a cancellation voucher.
