Horrible experience for both online and in-store services. Purchased a brad new dash cam from BestBuy online and paid for installation in store. Did not have a chance to check the device since when I showed to the store for installation appointment they asked me to out and wait. After finishing the installation, they gave me back a package which clearly stated the device was an open box. Talked with the store manager and online customer service, they both refused their responsibilities. The store manager, Steve, at Harlem and Irving IL location was extremely unprofessional and rude. He talked over me when I tried to explain the situation. When I asked him for a movements to listen to my side, he said out loud “NO” and hang up the phone. He behaved like a child and uneducated person. I spent a whole day to dove there and talked with both parties but both of them kept pushing the responsibility to other. As a business owner, this is not how you treat your customers or at least a human being because you do not respect people.I will never be back to BestBuy ever again!
