Microsoft Microsoft is forcing me to purchase a new surface when they lost or destroyed my old one Nationwide

On last November I bought a Surface. It was working fine until the upgrade to Windows 10.
The I went to Microsoft support on-line. They couldn't fix it so they sent me a new surface as I sent my old one for them to repair as it was on warranty.
I don't know what they did to my old surface, but what they are saying now for more than a month, is that the video port was damaged (I never used it. I not even have the compatible cable for that port!! So it came already broken from factory for sure!) so I lost the warranty, so I have to pay more than 200 or 300 I'm not sure to keep this new surface they sent me. I said that I don't want a device that is as detachable as surface and that I will send it back and that I want my old one back.

They said they lost it and they cannot do that and that the only option I have is this one: Keep this one and pay them. So, in other words, they are trying to force me to buy a new surface against my will! That's absurd!
