Im sorry to break it to you, but clips submitted as evidence for your ban cannot be used for appealing. The clip that you are talking about is very against you when it comes about wheter you were hacking or not; Just "assuming" that the other player was flanking behind the rocks, to just take cover from him before even seeing him and hold his push shows a lot. (just flicking to him as he was half-way flanking and hiding from his angle is more than enough).
As for more proof, i would suggest submitting some sort of clip of your gameplay, showing how you gameplay looks like while killing other players or making some nice play against others (the more the better).
