I saw that, it sounds like the problem is that work was commissioned by "Iain" and then the box went to the seller, and now onto Adam, so its changed hands twice since that company saw it.

To me the logical resolution would be for the seller to put Adam in contact with this Iain, and hope he is a decent chap (no idea who he is) and will help out with taking it back to the company that did the work to get it fixed?

The guy adam bought it off, sounds like he is just stuck in the middle and never personally had anything to do with the box?
