I was getting calls from a collection agent that took great pride in flat out harassment and rudeness to the point he made the wife cry. He made the mistake of giving his name one day and I already knew who he worked for so with a little google help I found him, address and all. Next time he called and got smart I asked him if I could come over to his , named address, and talk to him about this bill and maybe his wife, by name, could bring us some milk and cookies. Click and no more calls from this asswipe. By all means mess with them back if you can.
