Banned For No Reason

I was playing ranked last night and i lost my promos and i stopped playing and i woke up tried to login and it said i was banned. Idk why i was banned and the only thing i can think of is i have 1 game where i built full lethality kayn andw the enemy sona built full ap and i 1 shot him/her because i was fed and he/she said that i was cheating because he/she said none of his/her abilities hit and he/she reported me for cheating. there no other reason why i would be banned. the only other programs i use that attaches to league is overwolf and iwilldominate uses it. There are no other programs i use.
