I pre paid for my booking on line with a VISA card several weeks prior to using the car parking facility ,however, when I departed from the car park , as per the instructions ,I inserted my ticket into the machine at the exit barrier and strangely a cost was displayed - £169 !!! I pressed the button to speak to an assistant who was rude and very dismissive and not apologetic at all - He was really awful and like i said it was a pre pay and I should not have had to waste my time ldealing with this when I should have been on my way - then as I say i had to deal with this cretin who eventually let me out of the car park Overall a dreadful experience
