If you ever have unordered merchandise problems with WATS-line hustlers, you can deal with them more effectively if you understand your legal rights. If you receive unordered merchandise, federal law, as interpreted by the FTC, says you may keep it as a free gift. If, without your express agreement, the seller substitutes merchandise differing from the merchandise you ordered with respect to the brand name, type, quantity, size or quality, the substitute merchandise can be treated as unordered merchandise. You also may refuse a shipment arriving by U.S. mail if you do not open it.

To avoid misunderstandings with the company sending you such merchandise, contact them, preferably by certified letter with a return receipt requested. If you are sure the merchandise was never ordered, write the company stating that you have a legal right to keep it as a free gift. Keep a copy for your records. If you believe the sender made an honest mistake, you can offer to return the goods at the sender's expense. Of course, if a bona fide order was placed and you receive exactly what you ordered, you are responsible for paying the bill.
