I've had good luck with their support on the few occasions that I've needed it. I'm not sure what anyone on this list can really do about your problem though.
I dump all of my ebooks into a Strongspace[1] account. For $8 / mo. it's well worth it (I use it for other backups as well). Between this and my Safari account, I rarely buy paper books anymore.

I gain nothing from the plug. I've just had a very good experience with their hosting.
