We picked up the car at Victoria Station and headed straight for Greenwich. When we got there, the parking lot was pretty spacious and we felt that parking here was free, so we didn't think much of it. After we came out, we found that we had received a ticket. I went online at https://parkingservices.itsvc.co.uk/RoyalParks/notices/TicketDetails.asp and input the Vehicle Registration Number and Excess Charge Notice, but they said You must type a Excess Charge Notice and a Vehicle Registration Number. Clearly my input was not wrong. It's been three days now, can someone please tell me what's going on? What should I do ? United Kingdom Q&A
