14-day ban with confusion

I got banned for two weeks and I'm genuinely not sure what I did. I DID look at the other topic that was posted to see what could've happened in my situation. But in all honesty I am not sure. I haven't been toxic (main reason being it's my fault if I am toxic due to my 4 fps every game for weeks now which I just fixed). I have never been racist at least from I have remembered. Never have done sexist/sexual remarks which I know for fact. I actually have been getting honors recently (every now and then). And as for me even talking I haven't been due to that chat log delay with my old lag. I understand that some toxic comments do get you the ban for two weeks but I haven't even been able to do much to be toxic at unless it's a game where I can't land skillshots which in the case I get mad or in the case the enemy team is absolutely deleting me.
