True story: I owned a small business in the late 90s. At some point we had a billing dispute with Sprint long distance. Briefly, we required our (large) telephone bill to be sent to us electronically (diskettes at that time) so we could rebill our customers. For some reason which I don't recall, we only received the paper invoice for a month or two. Every time Sprint called looking for payment, we told them to just send us the electronic data and we'd pay the bill. They never did, and eventually it got turned over to a collection agency, which began hounding us. When that happened, I created a fictitious lawyer working for our company and had him author a sternly worded letter to Sprint. It reiterated the facts, firmly stated that we have no intention of paying, and demanded that they remove (I recall using the word 'extirpate') all traces of this obligation. The amount in dispute was much more than $100, so the time involved was worth it. I mailed the letter and we never heard anything more about it.
