Getting penalized just for saying that you will report someone

So long story short, a guy on my team said that I "should get cancer and die" and I wrote "muted + reported" and I got my honor level removed for that .... anybody else with similar problem? I dont really care about the chat restriction which was also applied I just want my honor level back? When can I start getting honor again(I was at level 3, and lvl 5 honor last season). I can post the chat screenshots later and the response from support riot which told me that there is "nothing they can do" and that the ban is exactly because I wrote that I will report that guy .... "threatening to report someone is toxic behavior" their said ... how would you react in this case?
