So thanks Best Buy! For either not training your corporate customer service, your in-store customer service, and wasting our time! We wouldn't have bothered to try and return it if we hadn't been given some idea of a "buy back".
So basically...if Best Buy's super-helpful corporate customer service team can't actually *do* anything for you, they recommend coming into the store so the customer services workers in there can make you feel like an idiot, blow you off and waste more of your time. This isn't the first time this has happened.
