Walmart complaint: Release My Money

I’m an aging, disabled 53 year old woman that is not rich, but I use to love Walmart! I recently decided to move to Texas to be with my son before my health declined. I needed a luggage set and found one online, but I had to cancel the order because the shipping was delayed and I wouldn’t get it the time frame I needed it. That was July 26, 2022 and I still haven’t received my money back on my card to this very day! I’ve been struggling because of Walmart! I’m not able to buy anything I need or pay anyone I owe because my card is negative! Walmart has put 2 more charges on my card that I didn’t authorize and didn’t release my original payment back to my card!! My card and bank are not happy with this situation, but can’t seem to do anything about it yet! Now, I took back a luggage set that I had to buy in store because the first set was delayed and I canceled it, no refund from that either!! $138, $159, $49, $103 is what walmart owes me and will not do anything to this day!! I’m so tired of calling and explaining! I’ve called a million times, but nothing resolved!!
