Having managed to contact the agent this morning and receiving a 'we send it to you when we get it, but have no idea when it will come, response', I researched and called the EK sales office in Malta and found a very helpful lady (who I won't name here) who took ownership of the problem, contacted DXB, confirmed my bag was enroute and says she will personally check that it arrives and coordinate the delivery to my home.

First class service and much appreciated. ^

Edited to add that she was as good as her word and called to confirm the bag had arrived and has cleared customs.
