My ex boyfriend got me permanently banned

Hello everyone, I don't know what to do, I am experiencing emotional stress because I've spent nearly 1500 dollars on this account. My ex boyfriend who lives with me on the same college campus compromised my League of Legends account, and said some very nasty things on chat. I was skeptical at first (thought that it was something I said), but when I saw the chat logs I realized that he was trolling on my account. I don't know what to do? My blood pressure has skyrocketed and I am not feeling really good. He has managed to destroy my progress of 3 years.
