Good luck with that, Elizabeth. My husband and I also had a horrible time with a landlady on the Isle of Man! There was a bad leak coming from the toilet and running along the inside of the walls. Her daughter told my husband to "stop causing trouble and that it was just the plaster walls drying out" when he described the problem. 12 weeks later after several colors of mold appeared throughout the apartment, the builder finally showed up and said, "oh yeah, there's a problem." DUH! Lots of my things got ruined from the mold that even grew on the inside of our wardrobes. We made the necessary phone calls, but were told as long as the landlord was taking steps to fix it, we had no recourse. Ok, yeah, they finally got a plumber to fix the leak and placed an industrial size dryer in the tiny apartment for the next 6 weeks, but you can imagine the nightmare.
Anyway, as you are discovering, the Isle of Man is not an easy place to make things right. Try to see if there is any legal aide available and keep us posted.
