Initially I received no confirmation for several days and had to make numerous phone calls to resolve this. 30 minutes before arrival I called as requested. On arrival I called again and was advised they'd be 5-10 minutes. After 20 mins I called again and was advised the same and that traffic was causing the delay. I don’t accept this as they must account for traffic conditions, plus they had notice of my arrival. When they did arrive approximately 40 minutes after my arrival I was told as my booking was for 0800 they wouldn’t arrive earlier. On return I called as the flight was early to ask a driver to meet me. I was advised I have to wait until the original time booked. I became quite upset explaining I was asked to call once at security, therefore I was expecting them to arrive as soon as they were able. It seemed unfair to ask me to wait another 2 hours as flights can be unreliable and the time booked is always an estimate based on arrival time. I then agreed the driver would call me on arrival at the car park to avoid me waiting by my car as it could be up to two hours. Over an hour I called them, no reply. I then got a call stating my car is there. I arrived a few minutes later and no-one was at my car. I called again and was told the driver left and my key is on the front wheel, I explained this was not acceptable service and they hung up. I then had to pay for over 30 minutes parking as they hadn't advised me my car was there earlier. I wrote all this to complaints department but have had no response. I recommend you do not use this company, not good service at all.
