Arrived at the parking following the instructions but the barrier did not recognise my registration so no ticket was came out. Pressed the button for help, told me to take the ticket and all would be sorted. Came back from holiday and the ticket now wanted over £200 despite the fact I had already pre paid for the parking. Pressed for the help and the person kept telling me I hadn’t paid for the multi-story parking even though I was looking at my confirmation email with the words “multi story refundable parking”. Eventually and very rudely let me through. Would be very careful when using this service.
