Best Buy Shorted Me $70 When I Returned Stereo Equipment

Ashley says she succumbed to a high-pressure upsell in car stereo equipment at Best Buy based on a free installation pitch, only to decide she wanted to return the stuff. When she completed the return she found out the installation wasn’t free, but discounted to accommodate a nonrefundable installation fee.

She writes:

Best Buy has cost me a LOT of time and money over a car stereo install. They LIED to me [in the Phoenix area] saying I was getting a free install, talked me into [nearly] 300 dollars worth of equipment when I made it clear I really only wanted to spend 200 hundred, and took FOREVER to install my stereo.

I exchanged it in Tucson and was all of the sudden the promotion that I was offered didn’t exist (what? this is a huge corporation, why aren’t sales the same all across the board). Tucson did the RIGHT thing and waived my install fee and gave me what I wanted, but I noticed that I purchased only $180 worth of equipment but was told it was an even exchange…and it was because they lied to me at [the Phoenix Best Buy] and said the install was free when they merely took the discount off the equipment.

When I called the general manager at [Phoenix] and asked him to please refund my 70 dollars he was really rude to me and refused to accommodate my request even though I still have thousands of dollars in electronics I need to purchase, so I got a little hotheaded and told him he would never get my business again, but I want to make sure that since I can’t get my 70 dollars back, Best Buy loses a LOT more than what they robbed from me.

What should Ashley do to get her money back?
