Apex Match Making

I've been playing ONLY Apex Legends for about 7 years now & season 29 & 30 SBMM is so bad I'm tempted to stop playing. 96% of my matches I am placed bottom of the lobby (redline far left of grey box) I have over 50 screenshots to prove that it's broken. 

Its got to a point that it's unplayable, it's not enjoyable at all, I'm am the cannon fodder for all the other players & our team gets taken out very quickly due to positioning. 

Really need your support on this because it's shocking!
