Really horrible experience, don't choose this car park. My car got locked in the car park and I have to pay 100 pounds. I received no feedback or refund from the service desk! I stopped my car at the NCP Portman Square parking lot on Monday around 2. As I was leaving at approximately 3:45pm, but I cannot leave the car park as both gates were malfunctioning. Together with 7 other customers, we waited at the exit gate for over 45 minutes. We have tried to contact the car park customer services and support team, but we received no response! In the end, I had to leave my car at the car park due to an urgent meeting. Because of this I have to pay 100 pounds extra parking fee.
