I would say you couldn't find a more responsive company.
I've had an order sitting in Limbo with no actual updates beyond "It's still backordered" for 10+ weeks now. They've fudged the Backorder date on the website twice, and now it's just a nebulous '4-6 week lead time.'
I could (should?) have had a PS Audio or Cambridge unit months ago if they'd been honest that they have no clue when they will be able to fill my order.
They are responsive in that they respond to my emails with the equivalent of 'sorry, kthxbai' but at this point I'm mostly keeping the order to see if it *ever* ships.
