Why am i kept queuing with blind mice?

For 3 games, i always end up teaming with players which are completely no brain included and no map awareness. What even tilted me is that they kept chasing like bots while opposing team backdoor for free. I feel like I had been tricked to play with bots. Cannot secure 4 dragons is one thing but letting opposing team stealing baron while we are all in it is beyond any words i can comprehend.
