What is an extended warranty? We were under the impression that it is a plan that extends the original manufacturer’s warranty, paying for repairs in the case that a consumer product is defective in some way that is not the owner’s fault. That’s what Pam thought, too, and she purchased one for the new Westinghouse TV that she bought from Best Buy. When the set broke down–six months into a four-year Geek Squad service plan, naturally–she tried to get both Best Buy and Westinghouse to repair the set, but no one carries the part she needs, and Westinghouse isn’t picking up the phone. Literally.
