However, drapes and blinds purchased and installed by consumers are not regulated by any state agency. Consumers can contact the business where the sale was made. If an agreement cannot be reached, consumers should contact a mediation source such as the Better Business Bureau, Small Claims Court, or a local Consumer Protection Agency.
