I am a pensioner who has now received two threatening letters from an organisation called control account plc regarding a so-called parking ticket picked up in the car park of my local Morrisons. It was originally about £30 but has now risen to £95 which I cannot afford. I parked, went across to the Job Centre to do some business, returned to shop at Morrisons and found the ticket on my windscreen when it was time to leave. What can I do? I REALLY cannot afford this.
