What kind of cog was it? I have read of numerous instances of the cheaper stamped cogs and the old Surly cogs stripping hub threads. Both are relatively thin (Surly has since redesigned their cogs so they have a nice wide threaded area). If it was either of these types of cog, particularly an old style stamped one, I don't think the hub company is at fault. If th e shop selected the cog for you and put on a cheap stamped one then I suppose d they are at least partially at fault...
Good luck :^)
