I have now received a letter from their solicitor who has made it clear that he wants me to respond to it with the sentence "there are some points made in your letter which in my view require clarification."
I have to say Ronnie that I don't read that statement as a clear request to reply. It seems to state to me that they are simply clarifying their position with you.
Sending them a bill for over a grand will certainly make them stand up & take notice though
I look forward to the next installment.
Was the invoice the only correspondence you sent them at this stage?
