Your holiday was trashed because of the Ash-Plume disruption. You, and many thousands of others were negatively affected in some way. I'm sorry, I really am: You have my sympathy. I wish it hadn't happened and hope that it won't happen again.
You appear to be searching for some sort of 'smoking gun' that will prove beyond doubt that you are the victim of some sort of airline cock-up or conspiracy: It is unclear whether this is for use in some sort of claim or not.
You are unlikely to find what you are looking for here: This will be a complicated situation and none of the participants will have the full story. You are welcome to continue if you wish: I would suggest that you are wasting your time however.
