Absolutely shocking customer service from TUI. Having booked 18 months ago, I was upset to see that our flights had drastically changed on the outbound and inbound to awful middle of the night times. Although I appreciate that changes do happen occasionally, I could also see that they had a much more civilisised time departing earlier in the day so called to see if we could change and pay any difference in the flight cost. After waiting for an hour on live chat with no response, 40 minutes on the phone, and lots of of back and forth with his manager, he advised that they cannot just change the flights on the booking and it would have to be cancelled and rebooked resulting in a £2,000 price increase! Absolutely disgusting response. I was more than happy to pay any additional cost for the increase in flights (both flights were TUI flights so I know they wouldn't have incurred any internal charges to change them) but absolutely not £2,000 to 'rebook' my holiday. I didn't want to change my holiday I just wasn't happy (who would be) with the god awful new flight times. Asked the representative to speak to a manager and his response was 'we only have managers to look after staff and not for customers so you will need to fill out an online form (and wait 28 days!)' Having travelled with TUI most of my life, I let 2 initial poor experiences slide beacause I wanted to give TUI the benefit of the doubt but after yet again another example of poor service and actually just greedy behaviour, I will not be travelling again with them.
