The problem with programmes like rogue traders and watchdog is that they use lazy journalism tactics.
So while it would be easy for them to expose this company and their underhand practises, it would be counter-productive to all carpet cleaners unless they were to explain exactly what a customer should expect from a professional, trained, insured and competent business.
But of course that's not going to happen, all they want is the shock value of the rogue trader.
For every scumbag out there, there are thousands of reputable tradesmen who never get a mention - hence every builder, for example, is tarred with the same brush.
