Big problem with autofill

I don't know about you guys but i've been autofilled for quite a lot now ever since the new patch came.I generally choose mid as a main and bot as a secondary and most of the time i would get my secondary as my role.This does not happen for 1-2 times tho.It legit just autofills me into my secondary all the time.I've been autofilled to my secondary for 4 games in a row and it is honestly quite tilting when you wait for a long time in queue then get 4 straight games where you don't get your most desired role.Not to mention getting matched by apes and flat earthers that play jhin jungle,tahm top and xin zhao adc.Plz kill me >.<
