How to write a letter of refusing to pay a bill?

Trust me, you do not want to go there no matter how angry or irritated you become. On the average a debt collector doesn't actually know if he's connected with the correct party when he spits out duns.. By your reacting to his cheesy attempts, your confirming that indeed he found the right party and that will just make him escalate his efforts (as the law allows).. Your best tactic is to ignore the letters and always answer the phone with different openings (ie: your town police department.. jack in the box, may I help you? the number you have reached is no longer in service, this is a recording.. etc.) he of course will get wise to your attempt but it will be too late because now you will know that he'll call back within minutes so, when it rings pick up then set the receiver over to the side and when you hear it beeping you'll know he hung up.. If he calls after nine o'clock you can report him to the phone company and they will put a tracer on it then turn thease over to the police who will contact him. I'm going on and on (mainly because I too can't tolerate low life bottom feeders) bottom line, do not give this toad any more info then he already has.. if it concerns a non-collaterial bill then he's just out of luck but if it has to do with something that you've already returned then he hasn't got a leg to stand on.. Forget that bozo.
