1. Banking Insurance Regulatory Bureau: If the products forgotten by banking financial institutions are charged at will, you'd better call the Bank of China Insurance Regulatory Commission, which is the bank's supervisory department and the most effective complaint. The complaint reporting telephone number is 010-66279113. It is recommended that you reply to the question by email and send the details of the complaint to your personal ID card. Write down the address, name and telephone number clearly, and send it to No.5, Financial Street 15, Xicheng District, Beijing, which will be received by the Letters and Calls Office of China Banking Regulatory Commission, with zip code 100033. In addition, you can contact your local banking regulatory bureau.

2. Bank headquarters: If a branch finds out that it collects fees indiscriminately, it can directly call the bank headquarters if it doesn't handle it internally. This method is also more effective. The complained bank personnel need to face the processes of interview, communication, apology, punishment, rectification, recording and notification. If it still doesn't work, they should choose to complain to the Banking Insurance Regulatory Bureau.

3. Financial Office: What if it is a private microfinance? Many of them have no formal qualifications, so the industrial and commercial departments and the China Banking Regulatory Commission cannot supervise them. You can try to search the contact information of the local financial office and make a complaint call.
