Best Buy is an antiqued 20th century retailer that will soon be obsolete like Circuit City. You would think that a retailer that specializes in technology would invest in modern point of sale computer system to track all their customer transaction, but they don’t. They still operate under a 1983 business model which is why Amazon will eventuality put them out of business. On May 24, 2019 I made a purchase of a Polk Soundbar System in the Best Buy Florida Mall. On August 30, 2019 the soundbar stop working. I keep the box, but I misplaced the receipt. I made purchase using my debit card so looked up the transaction and made a copied of the statement to show proof of purchase. I attempted to exchange the soundbar at the 6300 Grandview Pkwy, Davenport, FL 33837 Best Buy location. I was rudely treated by the customer rep because I did not have a receipt. I conveyed to her that I have proof of the purchase and the box with the bill of lading that shows this product originated from Best Buy Florida Mall. I requested the assistance of the manager and, he exhausted all his efforts attempting to locate the transaction in their system. Unfortunately, he could not find it. If I would have purchase the soundbar in Amazon they would have a happily exchanged the product. The lesson to be learned is that Best Buy is no longer the best buy when it comes to electronics and customer service.
