What about Guangdong Jinke Daotong Technology Co., Ltd.?

This network company is a junk company with poor technical level and poor after-sales service. Call customer service, or don't answer the phone, or ring for a long time before answering. The voice and video of the person who answered the phone just woke up. I'll show you the chat records of communication with their customer service. The reaction speed is super slow, it can't solve the problem, and it will make you vomit blood. A small problem has not been solved for a month, and there is no salesman to follow up. I don't even know where to complain. . .
