Hi, Sorry to hijack the thread but I recently received exactly the same letter for the same amount. I was told to ignore as it was just a [problem] but 2 weeks later I received another letter threatning to take recovery action. After finding this site I fired off the provide proof of debt letter by recorded delivery. Which was received by Philips on 3rd feb. I today (8th Feb) received another letter dated 4th of Feb saying they are going to attend my premises to recover the debt. I have no knowledge of any unpaid bills and If it is genuine I would be happy to pay. I have 3 small children and I am worried that heavies will turn up to intimidate my wife while I am at work. Could anyone please provide some advice on what to do next. Thanks
