Walmart did not refund my money Nationwide

On 11/6/2021 I wanted to purchase an iPhone SE from the Walmart website. I tried to pay with my bank card, it was rejected 3 times, but the last time it was accepted and the amount was deducted from my card. When I spoke with the customer service representative, he told me that the order was canceled and the process would be reversed. In 7-10 working days, 10 days have passed. I spoke to them again. They told me to speak with my bank and they gave me a code to identify the reversal of the process, but when I went back to my bank they told me that there is no money owed to me and that if the money is reversed correctly, it will be refunded automatically, 42 days have passed and they still tell me the same. I wanted to do the last step. Tell them to call me Voice Service. I told them 3 times, but no one even called me with a picture of my IBAN and I didn't receive any money. They tell me the same thing again
