But a business has to follow legislation and laws laid down by government for example. I don't know what the rules are like in America - cos I've never been there. But you are not allowed here to sell something that won't do what you say it will do. You can't refuse to exchange something that is faulty. Walmart works to rules laid down not by them but by others - work health and safety, discrimination Fair trading etc etc . If they don't keep to these rules or they try to change them then yes you can complain to them or to whatever section of government's laws they are breaking.
