Did you use any of the expedited eMail addresses? There are number of folk on this forum who are UK expats around the world who have used these avenues and had thier application accelerated after 10 weeks.
The UK Government are obligated to keep you legally compliant in you country of residence in these circumstances. Obviously with out the full details it is hard to comment, was there however a mistake in your application for example? But, on the face it from what you have written, you may have a good case to take the Ombudsman
