Getting suspended because of comp bug

So I searched for a game as support. Waited for 2-3 minutes and went to check if it was still searching. I pressed cancel to re-queue, but I see “Unable to join queue while previous match is ending. Try again soon.” I try searching again but it says i’m suspended for 10 minutes! I could even talk to people IN GAME and they said I left the match, when I never even got thrown into it? And now I lost SR that I worked so hard for. Please fix it, it makes me want to stop playing when these things happen.

I got a screenshot if needed.
