1. Credit system delay: Sometimes, there may be some delay in the bank's credit system, resulting in the credit card points not being displayed on your account immediately. You can wait for a while, usually within a few working days, the points should arrive.

2. Unsuccessful transaction: If the credit card transaction is unsuccessful or cancelled, the corresponding points will not be received. You can confirm whether the transaction is successful or contact ICBC customer service for specific information.

3. Restrictions on points rules: Different credit cards may have different points rules and restrictions. Some transactions may not meet the points rules, or they may reach a certain amount to get points. You can check the credit card points rules to confirm whether they meet the requirements.
