1. First of all, you can try to contact the customer service department of Industrial Bank, explain your complaint in detail and ask for a reasonable solution.

2. If you are not satisfied with the communication with customer service, you can consider complaining to the higher authorities or the headquarters of Industrial Bank. Usually, banks have corresponding complaint channels, and you can complain by phone, email or written letter.

3. If the above two methods fail, you can also choose to complain to relevant financial regulatory agencies, such as China Banking Regulatory Commission (CBIRC). These institutions often have corresponding complaint channels. You can make a complaint by filling in the complaint form or calling their complaint hotline.

4. Another way is to post your complaint information on the Internet, such as posting related events on social media, or leaving complaint information on forums or complaint websites. This will not only let more people know about your problem, but also attract the attention of relevant departments, thus speeding up the solution of the problem.
