Having already pre-booked the car park I expected upon arrival the camera to recognise the number plate and raise the barrier, which did not happen. As we were running slightly late I just pressed the button for a token and duly parked my car. The token was deposited on our exit only for the display to show an amount of £108.00. When I pressed the help button I was greeted with an operator who with a condescending tone told us we should have used the help button when we first arrived. The issue was was eventually resolved without incurring any further expense.
