We had booked them for Heathrow Airport pickup for July 21. Unfortunately our flight was cancelled on July 20 and I emailed company asking for trip to be moved to Friday July 22. They refused unless we paid another $270 for 4 people. They refused to refund any of our fee paid for July 21 even though we notified them timely. Horrible to work with folks trying to navigate out of country travel from Heathrow to Dover Port. Do yourselves a favor and use another transport. I can provide excellent references for two we used while in country. We received excellent service from he other companies.
