Parked in NCP Exeter. My coins went straight through the machine so I downloaded the app which took an inordinately long time. The app would not sync with my bank details. I left after 20 minutes of frustration generated by NCP & i had not even managed to leave the carpark. I then received a £100 fine. I challenged it as I felt I'd been held to ransom. The fine was reduced to an admin fee of £20 but it was clear that my explanation had not been read. Im furious. I wonder how many people are being ripped off like this. This is criminal. I will not be using NCP again & will copy this review to every feedback site available.
