Helen, you are not alone. Some so-called supervisors haven't got a clue about up-to-date research. How they get the funding in the first place is open to question, especially as there are others who could do so much more with it. Have you considered getting legal advice? Lack of support (for 15 months!) and experience are problems that the department/university should have dealt with at an early stage. Sounds like some form of professional negligence.
