Hi Ma'am, We investigated your complaint and here's what we found out: We requested your flight number twice via email and we have not got a reply (please refer to the emails). Your driver left early knowing we must position the driver ahead of the time just in case the flight lands early. We had been communicating. Your driver was parked along Bath road and the flight landed at Terminal 3 Heathrow. When you called, the driver was cruising the tunnel and it was not easy to park at Terminal 3. Inasmuch as we have responsibility, it Is also helpful to check our communications, we had been communicating closely with the passengers as we used automation APART from the text from the driver. We recognised that it was a challenging situation not to have the flight number, we requested twice with due diligence on our part, we did not receive the flight number, we positioned the driver close to the terminal, it was not easy to park, on this occasion, your expectation on our service was short and the non-availability of the information was the reason. With care and diligence, we showed how responsible we are, apologies for the inconvenienced, you could also share how satisfied you were on your outbound trip which can be added into the experience. The success of our transfer service also relies greatly to the participation of our client which on this case, we did not have the informations requested. I hope there is a recognition on the efforts we exerted inspire of. Thank you for the business and we hope on any future requirements, you would consider us again and that all informations can be provided. We thank you for calling our attention on this matter.
