'He was getting ruder every time we spoke': Scammy business guy tries to bully administrator and gets shut down, loses sale

It's often the case that treating people with respect will net you the best result, no matter how frustrating you find something to be. That doesn't mean that you won't need to lean a bit of weight on an ineffective organization or bureaucratic nightmare; the fact of the matter is that, often, in these cases, being the squeaky wheel will get you the grease. But, again, you should always do this with as much kindness and respect as possible. Having been on the other side of this in customer service, I can tell you with absolute certainty that you'll get the result you want (or a result) if you just treat people like human beings.

Well, this scammer didn't follow this ethical ideal and paid dearly for it. After submitting fraudulent paperwork, their continued aggression earned him nothing but a lost customer.
