Don't buy home appliances in Suning and provide after-sales service? What should we do?

Suning's after-sales service is really rubbish. On the 20th of this month, I bought a Supor range hood in Suning.cn. I tried burning tap water on the spot, but the steam could not be absorbed. Later, I have been communicating with the customer service in Suning.cn on the phone. The manufacturer said that their after-sales workers must come to inspect the machine and issue a test report. If it's a machine problem, they can return it. After seeing it, the after-sales staff of the manufacturer said that the machine was all right and there was no fault, and no return was given. So I called 123 15 to Supor's Nanjing headquarters. After answering the phone, the staff will register the name, contact address and online order number of the recipient, and then there will be no news. Then I went back to the internet to have a look. I found the machine I ordered, and all the reviews did have forty or fifty bad reviews. After receiving the machine, the glass panel is broken and cannot be replaced or returned. This is simply a forced purchase and sale, leaving customers with no way to complain. Even if you can't use this thing, you have already paid for it. If you make money, you won't care about your customers. Who will protect the rights and interests of consumers?
