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.
Patience. Like the guys that complain I don't gank before 6 as ww, what exactly could I possibly do for 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.
