The 6:35 to Gatwick from Rosehall did not turn up. The Web bus tracker didn't work and the customer service number was not answered. Eventually a bus turned up at 7:30 and when we told the driver we might now be late for our flight he snapped: "You should have booked an earlier one then!' When we told him that we HAD BOOKED an earlier one he said that it had broken down. At every pickup on the way the driver found it difficult to open the door to allow passengers on. Several times he resorted to kicking the door in order to get it open. He then said that the electrics were not working. We arrived at the airport at 8:45 -five minutes after our gate closing time. We had to forego any chance of buying sunscreen etc as we ran through the airport to our waiting plane. We ended up without mosquito repellant and consequently were eaten alive and covered in lumps and sores. This is not the first occasion that National Express let us down and we have now vowed never to travel with this unreliable company ever again.
