@yan I had a number of conversations with him, in all of which which he seemed like a really nice guy and perfectly reasonable. Each time he assured me that he had every intention of finishing the work, and there was only a few hours left.

He knew very well that the work was meant to have been completed in seven days. He explained to me that the project had overrun because my friend supplied the artwork late. Which was a perfectly valid explanation for 1 week of overrun. The other 6 weeks, however, are not so clear...
