Terrible customer service, they don't care about you. Don't expect any service whatsoever.
I called 5 times on 5 consecutive days to rebook my ticket, and they couldn't get it done. I had to leave holiday earlier because they were unable to rebook my ticket due to unavailability of tickets; a problem in their software apparently! One day prior to leaving suddenly someone noticed my 1 star review on TrustPilot, and suddenly a guy called Ross started offering options. All of these options very expensive tickets that were no way close to my Flexible Ticket rate.
A bunch of crooks that don't understand how to treat a customer at all. I tried to talk to them, but now I am done trying to help. Stay away from this lousy business.
