Not only family tragedy, but if it was not the LDSs decision to take such a long time in between classes/sessions, then it is very possible that the economy failed him like it has so many others today. This has nothing to do with ripping somebody off. I am pretty confident that most companies that have closed over the last couple of months would much rather still be in business and making a profit. Sometimes businesses just have to close and if someone is not around to collect on something, then they suffer.
Now, if they were receiving the messages from the OP and ignoriong them, then I would say they likely do not deserve the benefit of the doubt. If, because they closed up shop, they were not getting any messages, then they deserve the benefit IMO.
