you got vindictive, and you got revenge.
I covered my ass legally, and stopped someone from continuing to falsely disparage me in an attempt to extort. I was vindicated, but not vindictive. Facts don't go away just because you ignore them. There are two other customers whose schools I could have emailed if I was just angry because of negative comments on this forum; they weren't trying to extort a refund out of me, nor did they lie about our business communications and agreements, nor did they publicly boast about how they broke the law using my work against explicit instructions.
the customer is legally entitled to a refund
Really? Under what law? We had a contract, I fulfilled it, he broke it. He doesn't get a refund if he's the one that decided to break the contract. You're making things up again, Buford.
don't know their legal rights
Neither do you, apparently.
over petty cash
Once again, there was no cash incentive for me to take the actions I took. The customer paid, received the work, and then attempted to force me to give him a refund by lying about the work and my communications with him on this forum and elsewhere. This is something he openly stated in an email to me, which was posted in the same thread. Then he disappeared. I made no money, nor attempted to make any money, by doing what I did.
no accountability
All of my customers have my full legal name, my real address, and full recourse to use the payment processors I use to contact me and adjudicate disputes. You need to stop assuming everyone operates in the underhanded and plain-old-dishonest ways you do.
