Is there a channel to complain to the coach?

Go directly to the Traffic Management Bureau (Traffic Management Bureau or Public Relations Traffic Management Bureau), which is the superior department of the vehicle management office. If there is a problem with the driving school, the Traffic Management Bureau will definitely take care of it to ensure that you have evidence in your hand. If you want to complain about the coach, you can try to complain to the driving school first. If the conventional method fails, continue to call 1235 1 (customer service hotline), 12328 (transportation service supervision hotline) and 12345 (mayor hotline).
