Too bad they do not give you support, but in my experience it is usual that it happens. That is why in the company that I work, we travel to China to establish a relationship of trust. That is why we directly provide the after sales service with spare parts, supplies in stock and our knowledge and experience in customer service.
There are good manufacturers in China, the problem is the cultural difference, although do not believe it affects a lot.
By the way … they never use their real names haha. Their translated names would be like “moon smiling to heaven” and things like that; They use several names and even use names of the countries to which their stores are focused.
