i know of a well established company who has been working for 2 decades claiming to clean carpets very cheaply but the truth is once they are on the job the price goes up as the clean does not include spotting=extra chemical =extra conditioning!!? = extra. need i say more. you will probably find these guys work on the same princible so dont fret as the people who get stung will revert back to people like you once they get over the mistrust that is.
