ACCOUNT GOT HACKED AND GOT ME PERMA BANNED ON VALORANT

I tried opening up valorant and was told i had been using third party software and was perma banned, i checked my league of legends account as well and saw all my friends were deleted which seems like the person who hacked me deleted my friends to avoid being caught and used my valorant account for cheats and as soon as i was banned moved on with my account and left it, i have not been playing valorant for over a year now and have never used cheats in my life, i've spent over £100 on my account and want it unbanned, please help!
