After happily getting my big brother laptop, I booted up league and found a message saying I got banned for usiding prohibited third party software. I got shocked so I wrote a ticket for tech support, narrating the story, but after checking my match history on op.gg, I found a couple of matches played 9 hours ago of which I'm unaware of playing in, so I'm 100% certain that my account got hacked and now I'm panicking. Plz help
UPDATE: I got my suspension removed. Thank you guys for the help and especially thank you Riot Support for removing my bann and for understanding.
