I recently took your advice to another reader regarding his fine for overstaying the permitted two hours at Aldi. In my case I incurred an £80 parking fine (reduced to £50 if I pay early) for staying too long at Heston Services. The parking enforcement company has returned my £10 cheque, stating that this PCN was issued correctly and legally according to DVLA code of practice for the management of camera controlled private car parks. I was using the facilities the entire time and find the parking charge wholly unfair. How would you suggest I proceed? They have given me a further two weeks to pay the reduced fine of £50.
