banned for nothing

Iv Been banned like 3 times now because of this. Always in arena when I finish a game in the ending cutseen a notification will pop up saying you have lost connection from the servers (something like that). It thinks I leave a game not finished so it bans me! It happened just now. 24 hour ban! Please fix this seriously. And please unban me. Has anybody else had these problems?

Literally just happened to me. Said I was disconnected then told me I was banned for joining a match then becoming idle when I played for literally the entire match. Pretty pissed myself
