I ran across this blog accidentally,I just stumbled over it. What I found on there is a worthy read for any professional carpet cleaner. It is a blog by a lady who went into detail about her experience with a carpet cleaner she had hired to clean her home. I was astounded by it. Should give you pause about ever ticking any of your customers off and not taking their complaints seriously. The complaint is about half way down the page from this link. Btw, I think this was a legitimate complaint.
