Answer to the question:

According to China's credit card regulations, banks are obliged to notify cardholders of overdue information in a timely manner and are not allowed to accumulate interest for many years. If the bank fails to fulfill its notification obligation and accrues interest for more than one year, the cardholder has the right to request the bank to return this part of the interest.

Details:

1. Credit card overdue notification responsibility: According to China’s credit card regulations, banks should notify the cardholder immediately after the cardholder is overdue, and clearly state the overdue amount, Overdue period and corresponding penalty interest and other information.

2. Restrictions on interest accumulation: Chinese credit card regulations stipulate that banks are not allowed to accumulate interest for many years without notifying cardholders in a timely manner. Therefore, if the bank does not notify the cardholder and interest accrues for many years, the cardholder can ask the bank to return this part of the interest.

3. Recourse: Cardholders can request the bank in writing to return the interest accumulated over the years. If the bank refuses to refund or cannot resolve the dispute, the cardholder can seek help from relevant consumer protection organizations or arbitration institutions to resolve the dispute.

Summary:

According to China’s credit card regulations, it is against the law for a bank to accrue interest for many years without notifying the cardholder. Cardholders have the right to ask the bank to return this part of the interest, and can apply in writing or seek help from relevant agencies to resolve disputes.

Extended information:

China's credit card market has developed rapidly in recent years. In order to protect the rights and interests of cardholders, the country has successively introduced a number of regulations and policies. These regulations clearly stipulate the responsibilities and obligations of banks in credit card business, including the obligation to notify overdue information. If the bank fails to fulfill its notification obligations and accrues interest for many years, cardholders can assert their rights and interests in accordance with relevant regulations and seek resolution through appropriate channels.
