Banned for No Reason

Hello,
I was playing a friendly game of SWAT when right after the game it said I was banned. I did not team kill and was active throughout the entire game. All the sudden it said we were defeated and when it went to the rewards, it said my connection was lost, I joined the game again and then connection was lost again. I have really good connection and have not dropped from the game yet. Yet, as soon as that game ended I was banned for no reason. This is ridiculous and I did nothing wrong. Please fix.

Banned Time - 4:15pm Central US Time
