Type Cover will not Connect

I’ve tried everything — up-to-date, restarting, turn off and on, troubleshooting, running device tests—and I can’t get in contact with Microsoft customer service. My type cover for my surface pro 8 is magnetically connected but it won’t work at all and the connection won’t register in the tests. Without the type cover my surface pro is essentially useless. I can’t type on the keyboard or use the type cover mouse. I’ve submitted a ticket for customer service and haven’t heard back yet. A service repair is like $180 for a type cover!? I bought your device like 2-3 years ago and it’s still in great condition. Haven’t even dropped it once & it randomly stops working. Wtf. There doesn’t seem to be a scratch or anything. What could I do to fix this?
