A 3-man premade group reported me - can I get banned?

So I played a game in normal draft as first time qiyana mid. our jungler also wanted qiyana, but because it was my last game I could play that time I just picked qiyana. That jungler was in premade with our top and adc and - just because I picked qiyana - gave me 3 reports. Also, they said I was just feeding all the time (especially the jungler flamed a lot) even though I had the best kda in our team and the jungler was 0/10 at the end of the game I heard these reports only count when the game detects you actually did something wrong. BUT my internet died twice for like half a minute that game, so I "didnt earn rewards for afk/leave behavior". Does that mean I could actually get banned?
