I get it - delays happen. I'm completely sympathetic to that. I would just like to be notified either a) it's coming on week x and we have confirmation that it's been shipped or b) they tried and they have no clue, it'll arrive when it arrives. I'd just like to be in the loop - that's all.
I've been in the position of a distributor and as a retailer in this. Sometimes there just isn't a solid answer because there isn't one person with all the facts during the duration of an imported item's journey. Many distributors and retailers prefer to be silent than admit "We don't know, it'll get here when it gets here", which does suck.
