Account banned

Hey guys my account got banned in june and the reason was Hacking/Using Malicious or Game Altering Software, but i never had any types of programms installed on my computer.
Yes, i sent them so many tickets about this but they just sending me the same copy&paste answer.
I was the only one who had access to my account btw. Since i cant get help from the Support did anyone had the same problem and know a solution?
Because it makes me mad that my account got banned for hacking altough i am a legit player :(
