Suspended for being toxic towards my 5 premades in team chat
Iv'e recently been suspended for being toxic in a game, turns out there was a "glitch in the matrix" and riot posted the wrong game log (since the log they posted made no sense as to why I would get banned). Today Iv'e received a response for my ticket saying I was suspended for a game I was highly toxic in but here's the thing.. I was in a skype call with all four of them and I have no microphone so I'm talking in game whenever they speak to me.
Don't get me wrong, I'm not saying I wasn't toxic, but if I was only toxic in team chat and no one on my team reported me, why was I suspended? No one was hurt by any of the things I said, we were all laughing and having fun.

Has anyone experienced this before?

EDIT: After talking to people at riot via the ticket I sent; seems to be that the system just activated by itself and decided that I flamed and should be suspended, without anyone reporting it.
After like 100 games of me talking to my friends using in game chat because I have no mic, it had to be now, 2 weeks before the season ends when I'm at silver 1 with 50 LP... FeelsBadMan :^ )
