Horrible service start to finish. Tried to amend a booking and chased them for weeks with no response. My flights were then cancelled at the beginning of May and they never got in touch. When I eventually spoke to someone they tried to charge me £150 for my refund. Travel Trolley have since said this is in their terms and conditions (which have been updated since we booked) and that it's the airlines' responsibility to refund us (again, not what they told us when we first booked with them, and not what the airline told us). Refuse to put anything in writing or over email, refuse to call back or keep me updated about my flights and i've only experienced rude staff on the phone. Couldn't recommend less.
