Your first attempt to get satisfaction should be through the store from which you purchased the product. Most stores will refund your money or replace an object for truly legitimate reasons. In fact, stores that sell anything relating to health actually want to know if a product performs poorly or is in any way dangerous. They are most likely unaware and will appreciate your comments. If the store is not able or willing to give satisfaction, the next step is to contact the manufacturer.
Many products give a phone number to call for customer service.
Even if there is no phone number, there may be directions on the packaging to follow for returning items with which you aren't satisfied. If neither of these outlets work, it may be time to call in the government. There are many different agencies that are responsible for monitoring products sold in this country whether or not they are made here. The following list appeared in the Tufts University Health and Nutrition Letter, September 1998, Vol. Contact the regional office first before attempting to talk to anyone at the government headquarters.
