Bought an AC1600 Router from Walmart and It turned out it didn't work!!

So I bought an AC1600 Router from Walmart. Since it was Netgear, I trusted the brand and THOUGHT I wouldn't need to keep the reciept because SOMETHING NEW SHOULD WORK. It turns out the PRODUCT Doesn't Work. So I tried returning it back to Walmart but they didn't let me Even though its barley been a week since I bought it. Tech Support told me if I could not return it there, I could call them back and recieve another one, Even them knowing I had trown away the reciept. So I called again after another 5 unsuccessful returns and it TURNS OUT NETGEAR WON'T EXCHANGE IT FOR ME EITHER. NOW I JUST WASTED $80 AND BASICALLY THREW MY MONEY AWAY IN THE TRASH.  NETGEAR I WANT an EXCHANGE of your defective Product. It's NOT MY FAULT you Sold Me a PRODCUT THAT DOESN'T WORK.  Please either Return me my money or Send me another one. I await for your response.
