[2020] Permanently Banned

Hello here is the owner of the account that was banned, My problem is this: I went to travel however to leave the computer not picking up dust (since it would take a while to return home) so I left the computer at my cousin's house so he asked me if I could play Rainbow six I said yes, but only on this account, but when I got home (yesterday) I put it in to the game and saw that my account was permanently banned due to hack, I went to talk to my cousin but he spoke who did nothing (I don’t believe him very much) so I came here to ask that if they can disband my account it would help me a lot, I thank you for your understanding
