I advance booked a 7 day stay in T2 West multi storey park. No problems on arrival but when leaving 7 days later I drove up to the exit barrier, expecting my reg to be recognised and the barrier to lift. It didn’t. The display screen showed only a video loop saying “insert token”. I didn’t have a token so I decided to reverse out and try a different barrier . This was not as easy as I thought, the traffic was heavy, the light was poor and the the gap narrow. I got too close to the guard rail and scratched the paintwork on my near side door. When I finally arrived at the control panel I found the same token video playing. This panel had a button labelled “talk” so I called the operator who asked for my registration number before releasing me. All in all, a sad end to my holiday.☹️
