...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...
Problem there is that not everyone uses the same technique!
I have come across numerous different ways of cleaning carpets, all of which are valid techniques and depend on carpet type, condition and operator preference.
Your average "Joe Public" will listen to Watchdog's "Expert" and decide that his way is the ONLY way to clean a carpet properly.
If you go into a custy's house and try using a different technique, you'll get met with the attitude "That's not how they did it on Watchdog!".
I agree that something needs to be done about the shysters in the business but give "Joe Public" a little bit of knowledge...
