Skyguy – the point I and a few others are trying to make is that you have to put yourself in the position of the person who is going to read it. If you put their backs up with abuse or agression then your chances of success are less.
As an example my wife and I had a weekend break with a tour operator a few years ago in the UK, it was not one of their hotels. I wrote saying “I appreciate this is not one of your hotels, but etc etc “setting out the facts, finishing with “thought you should be aware of this”. In three weeks I received a reply with an apology and 50% of our money back. That is the difference.
However, in some cases you won’t get the same kind of response and it is doubtful you would have received a warm response either way from the Brittania
