From your account of the incident, you declined to take the customer's problem seriously at all.
I don't see that it's reasonable to disregard the issues of a paying customer on account of their poor netiquette. They aren't a professional tester filing a bug-report, they're a paying customer with poor communication skills. I don't see that refusing to help them, and even mocking them, is an acceptable response. At the very least you're holding yourself to a low standard.
