Can anyone help with an answer to a parking fine that I have received from my local hospital, run by a private firm called Vinci. I was waiting in a "waiting zone" for my wife, left the car to go and get her, and returned to a fine of £50. This was passed to a Debt Collection firm called Roxburghe, without any further correspondence from Vinci. They are now hounding me with phone calls and letters, to say I will be passed to a solicitor if I don't pay. Is this legal? And how do they get my address and telephone number?
