Without revisiting the painful details, the gist of the story is that I felt let down, badly served and generally unloved by an organisation that had happily taken money from me for a largely negative experience; not entirely but, to my mind, mainly ascribable to its own shortcomings.
The conclusion referred to above resulted in the firm conceding several points of contention and parting with a less-than-princely sum in compensation with the result that I am now only about £2500 out of pocket from the experience.
We live and learn - sometimes.
