It took me 2 weeks to get from gold 3 to plat 3 and 3 days to get from plat 3 to gold 3 and idk what to do anymore. I am not playing bad, I am not toxic, I don't tilt-queue.

I tried solo queing duo trio nothing works i just cant win.

In my last 11 games I only won 1, I am team MVP in 6 of them, Match MVP in 2 of them, 2 I played bad and 1 I left because my team was toxic.

Please someone help me or give me advice on what I can do.
Thank you

(Also I am playing on EU, I am don't think this changes anything)
