Wrongfuly banned on cod mw 2019

I was perma banned in call of duty modern warfare 2019. I was trynna play some cod a few days after new years and saw that I was logged in my alt account. I did some digging and foud out my main account was deactivated or something. I explained the situation in my ban appeal that my account may have gotten hacked and I got banned anyways for “manipulation of game files” and “use of client”. I have never hacked once in it yet they didn’t care and still banned me.
