this keeps happening

I tell them not to do baron. I'm the jungler, what do I know? Oh and our adc's dead. That's why I said we shouldn't do baron. OF COURSE THEY DO BARON ANYWAY. The whole enemy team respawns before they finish because our adc wasn't there and we lose baron.

A few minutes later, deja vu. We only have 4 people, and we don't really need an elder. For some reason top and mid decide that we need an elder WHILE THE ENEMY TEAM IS AT OUR INHIB TURRETS and start an elder by themselves. We only had 4 people so I told them to back to base, we need to defend not do elder. Then the enemy mid laner walks over, kills them both, and grabs elder for herself. Teammates say "If you were there we couldve used elder to defend", which is total bullshit since if we were all at elder with them in base they would have taken nexus.

And this happens over, and over, and over again. It seems like every other game could have been easily won if not for extremely stupid objective calls that I, the jungler, tell them not to do. I play nidalee so I can give my team a nice early game, with plenty of kills and what not, and I very often do this. But if you check my op.gg you will see that I have literally not won a single game in pretty much forever and it's because of this! Teammates utterly throwing a perfect game because of an objective that I told them not to do.

I don't know what to do at this point. I really don't. My teammates just don't listen to me.

I thought being jungler meant that you make objective calls, and at this point I feel like I'm being flat out ignored.
