Pick up was fine from terminal 5 and driver very helpful. Return from Ascot Racecourse never arrived. No contact from company whatsoever. I only found out the taxi wasn't coming when I rang them. No replacement sent and they told me it would be 8.30pm at the earliest when a car could be sent even though they had my details that our flight was leaving terminal 5 at 8.55. This was booked early June so why take the booking if you can't deliver the service or have the courtesy to tell the customer in advance so they can make alternative arrangements. This has been a very costly experience for me!!
