    I am writing to complain about the poor service I received at your store. I ordered a subwoofer speaker online and chose the option to pick it up at the store. It was suggested that I have it delivered. I received a confirmation email that my order was ready for shipment and would be delivered on Friday 20 October 2023. However, when I arrived home, my order was not there. There was confusion about who had possession of the subwoofer. I presented my confirmation email and asked him why I was not notified of the delay. I was very frustrated and disappointed. I wasted my time and gas driving to the store for nothing. I expected better service from a reputable company like Best Buy. I request that you take immediate action to address this issue.
