Issue resolved
I have has a reply from EZY that satisfactorily addresses all the issues that resulted from my being denied boarding on the flight in question.
EZY have been unable to say why the correct compensation was not offerd but I suspect that this was a mistake within the handeling agents rather than EZY being at fault.
I now consider this issue to be closed as EZY have sholdered their responsabilitys both under the EU law and for my extra expenses arising from the inccident.
It also puts into perspective the some of the very rude and uncalled for comments from those above who failed to meet the professional standards expected of the contributors to this forum.
