Colin,
Why don't you start buying you cleaning solutions and sundries from solutions and hydramaster?
They are both local to us and you would have had immediate technical support right on your doorstep, possibly you could have got one of them to chat with the customer and tell them how it really is! I know that both Nick and John will bend over backwards to support their customers.
Also, you could have called me, there are not to my mind any expert carpet cleaners down your end so wonder who it could have been.
Next time you have something like this happen call me and i will do what i can to help.
Cheers Goron
