Bronze 4 teammates when Im plat 1 in arenas?

I got a match right after hitting plat 4, the game put me against A FULL 3 STACK PREDATOR with a PF that has over 50k kill while my total combine is less than 4k, meanwhile one of my teammates was silver 4, the other one hasn't even finished the 10 match placement. "We" (I mean "Me" alone) lose 3-0 with both of them still busy looking at the gun store until the timer run out and deal a total less damage than me picking the P2020 in a hot drop BR zone

this is a sick joke to make us hate the game even more and the fact that they ignore entirely any post complain about MM, especially arena point out how scummy they are. but hey don't talk mean words or we will send a bot to silent you
