Matchmaking in HL: does not work

the matchmaking in HL does not work. Every game master vs platin and all sabotage the game no diffrence who you got in team.

if you ask for help or want to talk about tactics to turn the game, peole say “go to hell” or “shut up and play” and report you, thats why we all play without ingame chat.

may i ask when we can turn on the chat on again? the affraidness of permamently ban is big couse, last time I didnt toxic anyone and got banned for 2 weeks, just becouse playing 20 games a day on holiday.

I have over 14000 games, spend a lot of time and money for my account. I dont want lose it just becouse bad matchmaking triggers.
