TOM100
I feel for you with your situation and you are quite right to vote with your feet and try elswhere. As you say Jet2 seem to playing fair with people (an airline I have yet to fly with)
Maybe to speed up your refund have you got one of the TUI Superstores nearby ? we got ours sorted immediately by the staff in the shop. As my local TUI shops in a shopping centre is indoors they for some reason still not re-opened. I travelled approx 30 miles to the nearest superstore (In a retail park) knowing it was open and as I say they did everything straight away, even offered us the refund but we wanted to re-book. It was well worth the 60 miles round trip. No more waiting for emails, no more phone calls, can just relax and chill to next year for the holiday. I worked at Edinburgh Airport for a while and both the crews for TUI and Jet2 were great maybe its the people higher up causing the problems.
I hope you get yours sorted soon
