I have never written a review before but please be warned that if you need to get a refund for a flight if you have to cancel for any reason, in our experience Travel Trolley (through an outsourced call centre) make it as difficult as possible. Should be very straightforward that if someone not able to fly = refund tax for flight. The email trail and number of calls are beyond belief and having to chase when promises are broken of dealing with, responding or refunding us 'within 24 hours' or '72 hours' has meant we are still awaiting a refund one whole year later!! And endless excuses 'need to check with IT department' 'the person who is dealing with it is not here' having gone through endless security checks! Be warned! Very frustrating and now a matter of principle to get the refund! Would be nice to get compensation for the time spent and general frustration but not holding our breath!!
