I don't know why Chess.com is so trash

During a game, I got disconnected. I had installed Opera GX just recently, so does not have much cache. And, I had really good internet. When the game disconnected, I reloaded the page but it didn't help. I tried loading other websites and it worked. I need a rating refund and the rating I gain after winning the game. If you see it, you can see I was completely winning. I was a clear pawn up with a terrible position for Black's g7 bishop and I had played Nf5, it just didn't occur on the board. Instead of spending your money on marketing and other stuff, it would be better if you could make your server better. Today, the whole day was like this.

I have cache problems with opera before but i just stopped using it

Well you should try switching to lichess, or maybe a different web browser
