Ranked after promos

I doubt this will be even looked at, but last season I worked extremely hard to get to silver out of bronze. I ended the season in silver 3. I do the promos this season and go 8-2, and yet I was put into bronze 3. I have heard of many many other people getting the same thing, and I for one am disgusted with this. If I do good if not great in these promos how is it fair that I get demoted to bronze, but not just bronze it has to be bronze 3. I am highly upset and I am for one am tempted to not play anymore, how I put in multiple hours to get to silver then demoted just like that? It is embarrassing and I do hope you fix this in the future. What is the point in doing your promos if I am getting demoted anyways? There was absolutely no point in me doing good in any of them. I could have bombed and went 0-10 for them and ended up where I am. I am highly upset with this Riot. I apologize for the rant, I just know I am not the only one who feels this way!
