Factory keyboard defect - letter “u” - chuwi lapbook se

Dear manufacturer. I ran into a keyboard factory defect problem. At the very beginning, when I bought a laptop, I rarely spontaneously turned on the “u” key and everywhere in the messages I received - uuuuuuuuuuuuuuuuuuuuuu.
I disabled the letter using the program - mapkeyboard. The seller from whom I bought the laptop on aliexpres says that he has no parts to repair.
I contacted a local laptop repair company - they confirmed to me that this was a manufacturing defect and I needed to change the entire keyboard assembly. Can you help me and send me a part for repair?

I took a video and showed the problem

The manufacturer said that he could not do anything. Windose I can not reinstall sruzu begins sticking buttons - uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu. I turned it off programmatically from under Windows and use a temporary screen keyboard. Does the manufacturer recognize a factory defect?

The manufacturer wrote that the model was discontinued. They cannot send the keyboard, they also cannot take it for repair. They do not want to send a new laptop in exchange. I feel asked and cheated by the support team.
