Fair point. An alternative approach would be to press release the letter and see whether any of the local papers bite. The problem here is that most people pay these invoices because they are ignorant of the law. They look like Council documents and everyone knows that ignoring a council parking ticket is dangerous. The question TS should have asked is not how many complaints they have received but how many of these tickets are issued. The answer is certainly in the thousands if not the tens of thousands in Surrey. The fundamental problem here is that TS think small. I'm prepared to bet that if a small local business issued invoices like this, TS would descend on them like a ton of bricks.

Is 'Dave' harassing you in any way, is he intimidating you personally, stalking/spying behaviour? I know forest area and some of the 'community' can be a tad 'difficult' at times.
