Thank you. I shall do this tonight.
I have a couple of questions, when you say screenshot the page before and after. Do you mean the webpage (when challenging the ticket)?
Also should I realistically expect them to cancel it, or for it to go further?
I had something similar before where my car was wrongly towed in Waltham Forest. I had to take it all the way to court. but with the help of IvanLeo, won.
