The attitude of all the customer service staff in the company is poor. They never repeat their answer for more than two times when I ask questions. They are vary impatience, and making customer feel embarrassed about their inquiry, as they should apologize to him. No one answer for Wechat customer service. There is no reply for three hours about withdrawal and deposit. Even the attitude of customer service in all aspects really needs to reconsider whether Yongfeng is a formal trading place.
