2 Week ban for false boosting accusations

During the Season 7 Ranked season I spent a lot of my time playing norms after placing in Bronze III, not really caring where I placed considering I didn't finish my provisionals during S6. At some point in the middle of the season I decided "I think I've gotten better at this game, let's see if I can hit gold playing cheese top laners and if needed tanks since they're just as broken." So a few months before the season ended I played multiple champions such as Yasuo, Quinn, Pantheon, etc. and got pretty good results and managed to climb into Gold V. After reaching gold I decided on not playing any further since I'd already reached where I wanted to be. Skip forward a few months and I decided on learning other lanes playing different champions such as Malzahar and Vladimir. Only on the 4th I'd been playing Vladimir with a group of friends and winning my lane against some Bronze V Yasuo main who made the false claim of me being boosted, even in a normal's game. I've never shared my account and duoed with my friends in ranked so I ignored his threat. Afterwards, I just continued playing the game like everyone else and came home to having a two week ban and all of my rewards taken from me. Personally, I feel like Riot Support's ruling on removing my rewards was unfair and unusual, considering this is the first time I've ever been reported of anything even months after only playing normal games. Also, I'm very well aware that many others are going through this same situation and I would like others to also give their input on this situation.
