Remove ban history on my R6 account redhead.-

So i dont know if someone can help me here, but I hope so. Like 2 years ago a guy who I thought was my friend, played on my R6 account and cheated on it or queued with a cheater. Anyways, my account was banned for like 2 weeks back then and now im hoping the note will be removed, because its pretty annoying to tell people in the match, that this wasnt my fault. It would be great, if someone could help me! My name is currently “redhead.-”. Thanks!
