Just had an update from easyjet confirming that having validated the card I used to purchase the ticket from which they extracted the ticket price in about 2 secs.
They will pay my compensation to the same card in between 15 and 20 "working" days. ie 3 to 4 weeks. It is amazing how these big companies have the high speed electronic processes in place to take money in but steam driven process to pay money out! Still we will see?
