booked parking then a couple months later bought a new car and called them to change reg no. upgraded us to terminal parking which was great. however no one told us that we would just leave car (last time someone comes and takes photos ect then takes it away). after 40 mins managed to speak to someone who explained new system and when leaving just put ticket in a barrier would lift. Came off a half one flight in morning put ticket in to be charged £620. Pressed intercom and explained but they hadn't updated our reg. guy behind us is honking his horn and shouting at us to get a move on.. not a pleasant experience
