Sheesh. Half an hour on a phishing call followed by all of that worthless typing.
I usually just hang up immediately or if I'm in the mood for fun I drag it out as long as possible and then when I get bored I ask them if their parents know that they make a living stealing from ignorant people. Usually at that point they hang up and go to the net call but it's funny when some of them practice their Engrish swearing on me.
