Yes, plenty of times, never lost, last one was £310, cost me £30, got the lot back, all settle before courts date.
The best big bad debt was £28,000 about 16 yers ago for big PLC, Dupont, after 4 months, and soilicitors letters, the solicitor contacted them and as the debt was more thn £750 , he could put something like a winding up order on the company, i forget the official name he used, but because of the debt, the stock market would have to be informed by Dupont, needles to say the sent a motorcycle courier, from Wales with the check and got it within about 5 hours, great feeling of satisfaction, and stops people taking the mick.
