Thanks for the reply, if anything new happens I'll post an update.

My wife managed to get a Euro Car Parks ticket stuck on the car in December 09 by parking outside of Sainsbury's. She didn't notice the Euro Car Park signs and had parked in a disabled bay near the entrance. She didn't know there was parking enforcement in operation. If she had known she could have put disabled badges on display but didn't. She wasn't stopping anyone else from parking either side as it was unusually quiet at the time and there were lots of other spaces available. When she returned to the car a ticket was on it saying she had been parked there for five minutes without displaying a disabled badge. The ticket was for £50 or £30 if paid within 21 days. I read this forum at the time so we decided to ignore them. 23 days later came the letter saying the amount had been increased to £50 for not paying within 21 days. Recently we've had another letter from Control Account plc increasing the amount to £79.38 and threatening to obtain judgement against her. They state such a course of action may adversely affect your credit rating and would include costs, court fees and interest which may disproportionately increase the amount outstanding. The letter insisted on a phone call to them with 5 days or immediate payment by return post. I assume that was just an attempt to frighten her into paying up. We intend to continue ignoring them and go to court if necessary. I have a question has anyone reading these threads ever heard of anyone being taken to court or having there credit file damaged or do these [problem] artists always give up? Update 14/2/2010 We have now received another letter from Control Account PLC Stating the letter is their "notice of intention to make a civil claim against my wife". It states "this is your final chance to prevent litigation being commenced against you: if you ignore this warning then proceedings may commence and judgment will be sought". It then goes on to tell her how court costs, interest at 8% etc. etc will be added on. It then says if we still don't pay the bailiff's will be sent in to take our possesions and sell them plus a load of other ways they can forcefully take the money from us e.g attachment to earnings, charge upon our property etc. Obviously this kind of letter would intimidate many but as for us they have just wasted another stamp. Update 18/4/2010 I followed the advice on this site and ignored their threatening letters. I've heard nothing from them since ignoring their second letter.
