What kind of company is Guangzhou Tongxin Technology Co., Ltd.?

The company registered in Guangzhou is actually headquartered in Dongguan, with a total scale of about 50 people and more than 200 people. Only Guangzhou, Dongguan and Kunshan have branches. The boss surnamed Tong is a family-owned enterprise. He works in HR software, and the system sucks. He gives money first, then serves, and if he doesn't give money, he won't serve. The signed contract embarrassed the customer. Basically, I signed the contract with a down payment of 30%, installed the software at home, and then charged 50%, without any implementation. Even if the remaining 20% cannot be realized, it can only be forced to close the case, which has a poor reputation in the industry.
