The OTC seller of China of Binance Exchange are frozen for no reason

I have been an OTC seller on Binance Exchange for more than a year. A few days ago, the store was frozen by Binance for no reason, and the customer service could not give the reason for the freezing and the unfreezing process! If we don't let the opener send a notice, we will leave the store! Binance's malicious behavior can't be found by the relevant departments to complain or deal with. If anyone has similar experience, please help me! Thanks
