Following our return to Edinburgh Airport in the early hours of Friday morning after a 2 week holiday, we found that our car had a flat battery. I made a call to the RAC at 02.40 Hours, who advised that they could not attend until at least 08.30 Hrs. Your transfer bus driver who had dropped us back at the carpark previously noticed that we were still in the car park and after telling him what was happening, he advised that this happens all the time and that we were to press the help button on the pay machine and someone should be able to help us. On pressing the help button, I advised the responder that I had a flat battery and asked if he could help. the responder told me very bluntly, that he was on his own in the office and could not help. He then terminated the call. The driver again stopped and asked if we had called the help point. We told him the response we had got, to which he replied that was Bulls%*t and that he should have done something to help, and that he probably could not have been bothered coming out of his office. Given we had an almost 6-hour wait, we returned to the main terminal, to wait for the RAC to come out to us. The RAC eventually arrived at 08.30 hrs. We think that the very abrupt response from the operator of the help point was absolutely disgraceful, yes, he may have been unable to leave the office, but a more sympathetic and customer-friendly reply might have been in order. This review will be submitted to other Social media review platforms to advise potential customers of Plane Parkings lack of empathy and understanding for customers who might find themselves in our position. I would add, however, that all our interactions with the transfer bus staff were positive and friendly.
