That is something I had not heard. Perhaps a retcon I missed. What I do know is that D$P got mad because his Machinima handler wasn't instantly returning his emails, so he sent an email to a higher up he knew. Unfortunately for D$P, that person no longer worked at Machinima. The person probably called Machinima asking that they put a leash on D$P with instructions not to pester him as he no longer works there. Machinima sent D$P an email about this, chastising him for doing so and for not being patient. D$P got his panties in a bunch at being dressed down by what he considered to be an underling and told them if he was going to be treated this way he'd rather not be with them. Much to D$P's surprise, Machinima called his bluff and cut him loose.
Without powerleveling myself so I'll keep this as vague as possible, as someone who's job is also to handle complaints within the company shall we say, nothing will get a employee in bigger hot water with the help department more than not liking an answer the low level agent has to give you so the employee goes and screams and the agent's manager saying the agent isn't being helpful.
There's no "customer is always right" in this intra-company situation. DSP probably thought that he could both bypass and get into trouble the low level agents for "not helping" him; but the response that he got was essentially the same one most help desk managers would have given him: stop being a dipshit. We can't help you now but we will at the first opportunity, so just shut the fuck up until we can actually help you.
In DSP land, he was being talked down to because the help desk didn't drop everything they were doing to attend to him because he has bills to pay, dood!
