Because of these complications the commission took longer then expected and I eventually tried to refund the commissioner telling them that I don't think I'd be able to complete it, who became very disastified afterwards. With a disgruntled commissioner on my hands who refused my refund, I offered to complete them artwork in place of the Second Life build and the commissioner said that the replacement will "have to be at least a 10 page comic." Wanting to satisfy the customer I agreed to it and am currently about halfway through the commission, working on the comic in 5 page intervals.
But then the commissioner decided that I am to make them the orginal Second Life object anyways, so I'm expected to complete that with now a 20 page comic on top of it. (Note: the commissioner insisted on it being 20 pages after I tried compressing the story they've given into 13) The result is about double the work now for the price of one, and as a result has been taking up my time and filling a slot that other commissions could take up. The whole experience has caused me to stop commissioning for anything Second Life related and since then I've included a TOS point of not communicating except by email (the commissioner used to litterally hound me both on Second Life and on Skype).
What do I do? I've already tried refunding this person but they won't take it, and I fear they're going to report me on here if I inisit on it. Other commissions have gone quite smoothy it's just this one that's been troublesome.
Please note that I am reluctant to give any names because I really want to avoid a beware before trying to salvage the situation.
EDIT: Looking back on the logs the comic started out 10 pages, but over email I was given a story that I could only compress into 13 pages, only for the commisisoner to insist on it being 20. That's where the 20 page comic came from.
