At the weekend I popped into a shop to buy a couple of bits and forgot to get a ticket. I was only in there for 5-10 minutes so they must have been watching waiting.On the ticket it says that the charge can be paid in 3 days either online or by phone, however nearly a week on they still don’t recognise the reference number. My girlfriend has also tried to contact them via their website but we've heard nothing back.Do i send a cheque by recorded delivery?Seems a lot of people just recommend ignoring the ticket. Can this be done? A friend of mine has told me before that Private car park companies are reluctant to take people to court as losing would set a precedent.
