Eh.
If I'm jungling I usually have a plan. If you're not getting a gank there's probably a reason. You either fed really hard at the start of the game and a gank would just give your opponent a double kill, I'm going off to gank a more appropriate lane, or I need to farm a little because I'm falling behind. Play safe until we can get around to you.
Your first mistake is your assumption that Junglers know how to read. If they could they'd be able to read requests for help.
