Sorry I've taken so long to reply but I hope the following is of help.
I've now had a total of five letters from these jokers and one from their tame solicitors, Lawsmiths (same address). These have arrived over two and a half months.
Careful reading of the text makes me think that they are computer-generated - some contain minor factual errors in my case but could apply to others in similar situations.
They are all signed by Carly Shedlock (or it could be Shylock) who has given herself the title of Account Manager, each one more threatening than the previous.
The last one, received just over a month ago, was a one-liner:
"Please contact the undersigned as a matter of urgency."
Fortunately I didn't have any change for the phone. This sounds like a last-ditch effort to me. I suspect that if they actually had a case I'd have been taken to court long before now.
My CAB have also told me that the national organisation is reporting them to their local TSO.
One thing to watch out for: when I received the first letter I replied denying liability and sent it 'recorded delivery'. According to the Royal Mail tracking system it never arrived. This worried me until I managed to speak to one of the staff in their local delivery office. He told me that when companies receive lots of 'sign for' letters, the postman doesn't always get (read 'ask for') individual signatures for each letter! It slows him down so he might fail to meet the government-imposed targets for delivery times. When I complained at the post office I sent the letter from they denied this happens. To paraphrase Mandy Rice-Davies "well they would, wouldn't they."
Recorded delivery mail is only tracked at the start and end points of its journey. Registered mail, however, is also tracked at intermediate stages (sorting offices). So, It's probably worth spending the extra to at be able to trace letters at least for part of their journey.
I hope this has been of some help.
