Unfair ban for "cheating"

So, I just got out of a game. MVP'd as Iso on Fracture and my KD was 21/12. Got banned afterwards for cheating even though I don't cheat. I tried sending a ticket but once I try to submit it, tells me that I'm banned so I can't even send the ticket. I want to go pro in this game one day, cheating would be against everything I believe and grind for. I do have my POV of the game if y'all think it's needed.
