Need help may have been hack

When I try to log into League of legends it said I was permanently suspended and to look at my email for more information but it's not there. One weird thing I found was that my verified email is not even my email I use for League of legends. I need help to get my account back and hopeful find out who did this or it was just a glitch. May the lead my way. I don't want to make a new account ;-;. I will lose so much love I put into the game and my champions.
