I find this post very dissapointing.

There was a relatively minor unforeseen problem that was sorted out to your very generous advantage. You then basically went on to do all you could to ruin your own holiday out of a sense of misplaced and over-optimistic greed. This attitude of unrelenting pursuit of compensation come what may even when the problem is unforeseen and resolved well is one of the most distasteful developments of consumerism.

Go back and thank them for handling the problem well and giving you an upgrade.
