if you really want to stick it to them contact the better business bureau. had one of my co-workers do that to a sales manager at another best buy due to them not wanting to perform work that was paid for at the store i work at (boils down to the mighty dollar game but its not their money so...who cares? you'd think so at least), needless to say he doesn't work for the company anymore.
Little bit of show, little bit of go.
