Kicks me out of the game

I spent a lot of money on the game. While fighting the most important boss in Diablo 4, it kicked me out of the game! I spent many days and many hours preparing for the boss. While fighting the boss “Astaroth’s Lair,” I was kicked out of the game and a message popped up saying, “Disconnected from the network.” How could I have been disconnected from the network when I was live streaming and somehow the live stream didn’t disconnect me, but the game did? This is outrageous! I would have defeated the boss in the so-called “Astaroth’s” game and would have had the boss counted in the game. Unfortunately, because of your fault, I was disconnected from the game. I don’t know how you will do it, but please count everything in Astaroth’s Lair on my account. Please mark the boss in Astaroth’s Lair as killed and completed in full on my account. Otherwise, please refund my money for the game because it is your fault that I lost very valuable time in the game. Everything is recorded in detail here from 04:59:01: https://youtu.be/7UbUw4Srip8?t=17942. Please analyze it carefully and read everything thoroughly, slowly, and with understanding, and give me the completed boss and all the rewards.
