Apple Watch 6 overheating and now completely dead

My apple watch 6 (one year and 10 days old, of course) wouldn’t wake up the other day. I thought it needed to charge, so I put it on the charger and it showed the high temp warning (it was not due to external temp-it was in the 70s). I felt the watch and it was super hot, so I removed it from the charger to let it cool down. I tried charging it again a short time later, and saw a weird lightning bolt and squiggly line but it wouldn’t charge or wake up. I tried resetting it, and it won’t reset. Went to the apple store, assuming that a watch that costs hundreds of dollars and is barely a year old would be covered, and since my warranty had expired 10 days earlier, my only option was to pay for a new watch which I will not do. Has this happened to anybody else? I’ll use a wearable from a different company before I ever pay for another Apple Watch at this point. It’s overheated when charging since I got it, and that was dismissed by the apple reps as not a big deal when it was still under warranty-there seems to be something wrong that the company is not interested in making right.
