Here's how to talk to customer service. In this case, you're trying to return something at Best buy. I worked at Best buy for over 4 years and the best thing you can do to get what you want is to be nice and reasonable. Instead of getting mad and asking for a manager, be nice and understand that flattery will get you everywhere. If you shop at the store often, bring up your purchase history and let them know that you're a good customer.
