They never update order totals. Whenever I do order pick up at Walmart, Walmart places a temporary hold on my card. Once order is picked up, the total usually changes because items are out of stock. However, Klarna never updates the total. They will still charge you the hold amount unless you reach out to them and jump through hoops to prove the correct amount. It's super inconvenient. I've been trying to get an order total updated for a month even though I submitted receipts multiple times.
