Aliexpress.com Alibaba group I purchased a radio for my car. It doesn't work as described Internet

I purchased a radio for my car. It didn't come with any installation instructions. There was nothing to show you how the multiple wires connect to the radio or in my car. I contacted the company to get installation information. They eventually sent me an email with some information about the radio but no real diagrams on how to connect it to the car. They have some short videos on Youtube, but not enough detail to explain how everything should work or how to navigate to different functions on the radio. The radio is supposed to look like a Tesla radio. It is supposed to opperate the temperature controls in my car replacing the factory controls. I could not get it to work. I have contacted the company DLCLH, but they wanted me to skype the engineer instead of creating installation instructions, and including it with the shipment. I know some I.T. but it is still very difficult to sort out. I don't use skype even with my family. This is the first time I have ever bought a product where I was instructed to skype the seller for installation help. I was instructed to be mindful of the hours of opperation to contact the help desk. I also ordered a camera to connect to the radio, but have yet to receive it. It's been over a month. The radio came 2 weeks after I placed the order. I may not get a refund, but I want to do what I can to discourage others from being treated this way. They are definately not Amazon. I took a chance on them and got burned. I want them to lose as much busness as possible, if thats the way they want to treat people. I heard that negative feedback goes farther than positive feedback.
