Heathrow Elite Parking Park and Ride Reviews

I was going to give 5 star as on our way to the airport the service was excellent, helpful, timely and very polite. However, on our way back when I phoned from the airport I had a very aggressive and unhelpful response. In the end they picked us up, all be with a 45 mins wait, and it may even had been my fault for misunderstanding the instructions when to phone them, BUT politeness and courtesy to the client surely is paramount importance. Isn't it?
