ToS Team Not Actually Investigating

I have been banned for Competitive Advantage, In a game Ive have only ever played in Solo or Coop Mode. I have purchased one skin pack throughout my time playing. What is the competitive advantage to playing against bots? How does that justify a ban? If the ToS Team was actually Investigating these things they would know I had only ever played Solo/Coop mode, the only other time there was another player involved was when a friend was playing on xbox and joined the game while still in Coop mode! not even on the opposing team. no exploits were used, no external or internal software/hardware. just being banned because I played a game mode specifically included in the game with a friend on a different console, the team does not specify any reason, they offer no help, they leave no notes, just close the case leaving you to appeal.
