Someone hacked into my Valorant account

I just logged on today and saw in my career history that there were 2 matches played as Jett in competitive and ended with me being match MVP. But I barely ever play Jett and don't remember playing them, they must have happened in the last 24 hours because I was playing yesterday. (I also don't play a lot of competitive) I'm just concerned someone hacked into my account and cheated on it. Does anyone have a similar experience or knows what I can do? I don't really know how RIOT bans people but I'm worried my account just got added to the next ban wave or something. I sent a ticket to Valorant support but I don't know if they can help or if there is somewhere better I can go to. (BTW: I changed my password, enabled 2FA and clicked the option to log out everywhere so I think my account itself is safe)
