Unfair suspension

So, I got a 14 days game-suspension today, and from their reasoning I think it was pretty unfair:

Game 1 truttern: can you ward drake+ truttern: gj truttern: lux truttern: give them to him truttern: we need to focus on assasinating vayne and soraka truttern: no truttern: soraka is the reason vayne is alive truttern: yes please truttern: %%% kled truttern: greedy %%% truttern: give turr truttern: or not truttern: gg

So, to give some context, Kled and I was on very good terms all game, the "%%% kled" was simply a joke I made because he tp-ed bot to get a juicy wave I was headed for. He got the joke and it was nothing more to it. Also, it was most likely the Lux that reported me, since she reported the whole team for "being trash", "being boosted bronze players". I don't really see how this is sufficent for giving a ban, even if it was with bad intentions.

I don't usually comment in chat either, if someone is tilted or flaming I just usually mute them to avoid getting tilted. This is my first time getting a ban, and tbh I am pretty baffled by the whole incident. I have issued a ticket to riot, but do you guys think this was behaviour that deserved a ban? If this is what usually gets people banned then I understand, but I feel this was taken out of context and unfair.

Btw. sorry for broken english.
