I had someone like that once -- actually, a local professional outfit. I didn't need an explanation as to why they didn't get anything done -- they didn't get anything done because I demanded it back before they started. What I really wanted an explanation for was why it was taking so long for them to get started, and I got nothing but a shrug over the telephone for my troubles. When I came in to pick it up, I was so rage-y, that I didn't even talk to them, just demanded it back.
It is my understanding that they had previously gone out of business. Twice -- once priorly, once after my business with them. I have to keep an eye on them, because they've changed their names several times.
