Walmart Sold My TV I Bought to Someone Else

I bought a door-buster TV at Walmart in-store in Georgia, US. It was a Phillips 65-in 4K Android smart TV on 11-28-19 during the 6:00 P.M. opening. I waited for a very long time to get a shot at obtaining one. I managed to obtain one. I paid for it at the register with a receipt and with the reservation paper they handed out. After my wife and I finished shopping around 8:30+ P.M., we went to the back of Walmart to try to pick it up. Nobody was there. All doors were closed. We were confused. But because we already had so many things in the car, it was Thanksgiving, there were still many customers in the store, we would have to find parking again, and we still needed to eat our Thanksgiving meal at my parents' house we decided to go. It was getting late, and we had left our children with their grandparents. Thus, we decided it would be just smarter to end the night and pick it up the next day. The next day, 11-29-19, at around 1-2 P.M. I went back to the same Walmart to pick up the TV. I was so excited at the time. I came up to the customer support to claim my TV with receipt and the reservation paper in hand only to be lead to another Walmart employee. He told me I should have picked it up before 8 P.M. the night I had bought it because it was on a first-come, first-serve basis. He told me there were customers who had come by and asked whether there were any Black Friday special TV's left, and they sold them what was left that night. He told me all the TV's were gone and none were available. I was shocked. Never have I bought an item only to be sold later to someone else. It shouldn't be legal. That's against fair trade. He said he would ask the manager about it. I told him no one had told me to pick it up before 8 P.M. In fact, when a couple of people and I had asked a Walmart employee where to get the TV the night we had the reservation papers, he had to ask some of his coworkers because some of them didn't know. So if instructions weren't even clear to the employees, how should a customer know to pick it up before 8 P.M.? Nowhere does it say pick up merchandise by 8 P.M. on the receipt nor on their Black Friday catalogue, nor on the Walmart website. Even if there was such a rule, it would be very difficult to enforce. Not every customer is going to know this policy! Even the employees at the customer service that worked that day when I had come to claim the TV told me they didn't even know about the 8 P.M. rule. They felt pity for me after I explained how unfair the store handled the transaction. They offered me a chance to speak with the manager. I spoke with the store manager. I did not have a pleasant conversation with her. She kept pushing and asking me why I had not picked it up before 8 P.M. kept trying to investigate my motive for not picking it up at the time. I told her it wouldn't have mattered because I had bought it already. I told her the receipt was a record of the transaction, and that TV was mine already. She vehemently denied the receipt as a valid record. Her statement shocked me further. I wondered how in the world is Walmart so high-tech with their use of computers and scanners to not consider a receipt a valid form of record/ledger/tab? This manager kept blaming me instead, the customer, for not picking it up before 8 P.M. I told her no one told me about the 8 P.M. rule, but she kept arguing and putting the blame on me deeper and deeper. I was deeply disturbed at how this supposed manager handled business. She was trying to place the guilt on me when clearly they were wrong for selling my TV. I was really looking forward to that TV. I waited for a long time to get one. I lost $188 in discount savings. The TV is marked as $488 regular price and discounted to $278 that night. I am trying to seek help. I believe this was not legal. Once an item is bought ownership of the TV is transferred to me, and they had no right to sell what was already mine. No one else should be a victim to such practice where a customer pays for an item only for the item to be sold to someone else so someone else can get the discount. It's like saying you can buy the exact same item someone had already bought online, and that online buyer should have picked up their online order immediately once made available before someone else can buy it a second time. I'm sure there's a legal term for that. I called the Walmart Headquarters without any real help. I believe what happened that night was the TV was in such limited supply and greatly discounted that someone else wanted it, perhaps a store employee or someone they know. They just threw out the fact that the TV was already mine legally since I had already paid for it and sold it to that person. Imagine if that item wasn't a TV. Let's say it was the only rare limited item in the world, and it was of much greater value than my TV. You bought it already, but the seller decided to sell it to someone else because you should have picked it up 2 hours after purchasing it. That's simply illegal. I say 2 hours because the Walmart Black Friday started at 6:00 P.M., and they expected me to pick up the TV within 2 hours while I was still shopping. I don't think Walmart as a whole would have agreed to limit customers' shopping time down to 2 hours just to pick up a large TV. In fact like I stated we finished shopping around 8:30+ P.M. If I had picked up the large TV first, I wouldn't have had room for the other $500+ merchandise I had bought in my car. Walmart would have lost $500+ from a customer that night for enforcing a 2-hour pick-up rule. I don't think Walmart as a whole would agree to such a rule like that at all. I will continue to fight this until I get the fairness and justice I need. I was cheated. This should not happen to anyone else.
