Account Hacked and then Banned, While Asking for Help

I apologize for having posted this in the wrong sub-section beforehand.

I had quit playing League for several months, until a friend convinced me to play with him last night. I got on and came to find that I couldn't log in. I managed to put out a ticket and regained control over my account shortly after. However, as I finally logged in, I was met with a message telling me that I was being given a chat restriction. It was shown to me alongside a long list of toxic things that the person who had hacked my account had said. The first thing I did was put out another ticket in the hopes that this could be resolved without much hassle. Until then, I simply refused to play for a bit longer. I waited for five hours before I finally got a response. However, I didn't actually get a response. I received a permanent ban for using 3rd party programs. There was no human response to my plead. There was simply a middle finger. I put out another ticket hoping for this to be handled properly, but so far no response. Needless to say, I'm rather livid.
