I think you misunderstood me - I was not of the mindset that Cunard owed me money. Rather I expected them to call me to see if they could help me arrange another cruise that summer. Was that too unreasonably high an expectation?
I also kind of hoped that they would offer me an alternative at the same rates as I had paid for the original cruise but I now realise that pigs will have to doing a flypast my window first.
Plus I didn't get any loyalty points even though the cruise was paid for, though not taken.
