Generally speaking, the rejection of credit card withdrawal may be caused by the following reasons:

1, do not use credit cards often;

2. The repayment is not timely, resulting in overdue repayment;

3. In credit card consumption, the proportion of online payment is relatively large;

4. Suspected credit card cashing.

In addition, if you have a bad credit record in other economic activities, it will also affect the improvement of your personal credit limit. In addition, the card holding time is too short to apply for increasing the credit limit. According to the regulations of China Construction Bank, you can only apply for increasing the credit limit after holding the card for six months. You can also call the customer service phone of the bank for consultation.
