1, bill generation time: Credit card bills are usually generated on a fixed date. If your cancellation occurs after the bill is generated, you will see the change of the annual fee for cancellation from the next billing cycle.
2. Processing time for cancellation: After you cancel the annual fee, the bank needs some time to process it. This processing time depends on the bank's internal processes and time constraints, and may take several days to complete.
3. Annual fee refund method: Some banks will directly refund the reduced annual fee to you, and some banks may regard it as a fee reduction in the credit card bill. The specific refund method will be different according to the bank's policy.
