God I hate telemarketers, wherever they are from. The worst are the ones who can barely speak English though. Now I have nothing against people whose primary language isn't English. English is actually my wife's 2nd language and I've lived in another country and know how hard it is to learn a 2nd language. But for Christ's sake, if you're gonna employ someone whose job it is to speak to English speaking people, they really should know how to do it.

Usually I just hang up on telemarketers but sometimes if I'm bored I like to play with them a bit. One of my favorites is to to let them go through their sales pitch, saying things like "wow", "sounds great" etc etc. Then, when they finally go for the kill and try to close the sale I'll say something like "sorry, actually I'm not at all interested, I just wanted to waste your time since you're wasting mine". Most don't know how to respond.
