Why am I constantly matched with underperforming teammates

As of late my losses aren’t even close. All of my teammates get maybe a single final kill. Like my last game I had six, we had 2 players with ZERO and another with 1 and one with two. Please don’t say get good does anybody else experience this? I can’t just drop 30 with no help it’s so hard to even get a single kill when nobody else is getting kills
