Banned for intent for no reason

6/20/4 I cycled through 3 builds , I was forced to adc with a support due to my jungle and I having miscommunication then 3/4 members of my team started flaming me for not being able to vs a and a and then I was invited by the midlaner to help him as I couldn't currently have any impact on the game. I then got and tried the best I could to get my mid lanner ahead and we ended up seiging the whole mid lane and I followed every single order and request he asked such has different builds and play styles. We ended up back dooring and got 1 nexus turrent and pushed every single tower and inhibitor in the mid lane. No one on my team said anything about the current play style but near the end I had such a gold loss I was constantly being shut down but non the less I listened to our mid laner. In the end we backed off for it a bit and we rotated as a team and got bot inhibitor and then won the game. Then to my suprise I was suspended for 14 days (2 weeks) for helping my team win a normal casual blind pick game which I didn't give 1 kill intentionally all game. If anyone could help why a bronze player like me playing normals and trying my best is counted as intentionally feeding it would be appreciated.
