There are generally the following reasons for the failure of redemption of integral merchants:

1. Use special integral rules cards, such as Shanghai Volkswagen Dragon Card and China Eastern Airlines Dragon Card.

2. The card status is abnormal, such as expired or stopped.

3. There are too few card points, and the balance of points is less than 5,000 points, which does not meet the exchange standard.

4. The cooperative merchant has expired and no longer provides exchange service.
