False Reporting

So I just got falsely reported of using offensive language in a game... and i got a message that says "my behavior is not in line with..." but I didn't do anything... and when I asked the person why they reported me... they said because i was saying "accepting appologies". I said this because earlier in the game they called me "trash/shit/etc" and told me to "fuck off". So when I started to carry them... I said "accepting appologies"... I just don't want to get banned for something I didn't do. I have a long history of being a good teammate and a sportsman-like player. I don't think it's fair that I'm getting reported for things I didn't do and that could get me banned.
