Definitely was not the above thankfully. I have had a reply this morning which Im glad they responded quickly. They have apologised and going to lift the call. They have suggested that they may have done one validation on the PNR and then wanted to do another on my Aerclub account but to be honest that should not be needed once they see status on the PNR. Also why not explain this at the time. It's extremely time consuming and annoying. They need to find a quicker way.
They should have a better process while protecting peoples data at the same time. Im going to go through my account and see if I ever put my Mothers maiden name on it and if so change it so in future I will know its the one Ive made up. Id prefer a password on the account which is what a few companies I use do.
As suggested I will be calling after 1700 in future wherever possible.
