Some years ago some guy name "Jorge Accabado" apparently gave my wife's phone number when applying for some sort of credit. Now we get calls from credit agencies every now and then for this guy. Collection agents are asshole morons. One called up asking for the guy once - I said "I've never met the guy in my life, you have the wrong number" and he replied "Well do you know where he lives?"

Fucking idiots.
A friend of mine passed away a few years ago, way to young, in his late 20's. He had thousands in credit card debt - the credit card company's collectors went after his parents directly, and were calling them and harassing them and wrongly claiming that they owed the money now and would have to pay.
