Hello Thanks to all for top advice - I will be using it. Just an addition - all of these civil enforcement groups work for someone - so I've taken it upon myself to keep that 'cleint' in the loop. Can you imagine the impact on a particular shop (in my case Lidl) when I advise them I won't be shoping there again because of their subcontractors actions? The other effect of this will be to ensure that if I send 5 letters and recieve 5 letters - Lidl are getting c.c. on them as well. See how far customer service is willing to go when it comes to the next round of tenders for whomever delivers parking control for their company. Just to qualify this a bit further - Tescos suggest that the average household spend £4,000 or £5,000 a year at their shop. So the ticket company might make £90 off me (or they might not) but the ticket companies employer (Lidl) is going to loose £4,000 of my business for ever. Again thanks to all.
