On entering the car park the ticket was not issued ,I then had to contact the customer hut to ask what to do. He advised he could not issue the ticket either but as I was in the time frame for the short stay it should be okay, so just push the ticket as normal. On arrival back at the car park the ticket asked for £166 I then had to re verse the car and go to the hut again. HE validated the ticket to allow me to get out without paying £166. Last time I used this facility it worked like clockwork, this experience is not what you need before you fly or return to the car park. The issue of issuing tickets needs to be resolved.
