Trolls on your team when you're winning the game

So I'm in a game right now as Urgot top My enemy laner is Heimerdinger The lane is super chill, we're doing nothing but just farming endlessly and occasionally poking each other. Then, my teammates decide 'urgot needs help destroying the enemy's top tower' and yasuo comes into my lane. He gets me killed by baiting me into donger's turrets. Later, ashe wastes teleport to come in my lane, steal my cs, and bring the enemy urgot to my lane to kill me. As much as I pinged and typed, they wouldnt budge. I eventually just went bot to get my farmign back up. This is unnacceptable and ruined my fun.
