Walmart Grocery Pickup Needs to Pick It Up

My wife has been using Walmart grocery pickup for years now. When you create your order, it puts a temporary hold on your card for the amount of the order. When you pick up the order you have the option of refusing any substitute items, which would then change the total cost.

The way things worked at first, by the time I got home and opened my banking app, the final total cost had already processed. Now, though, it takes up to 10 days for the transaction to go through, and it often goes through in multiple components that sum to the order total instead of just one transaction that equals the order total. This makes the service such a bookkeeping nightmare that I no longer want to use it.

Last week my wife placed an order that came to around $85 dollars. The day of the order she refused some substitutions so what she brought home cost around $70. Walmart had $85 blocked out on our card for a week, until today when the block went away. But they STILL haven't taken ANY money. Eventually they will do a few transactions that will sum to $70. What was wrong with the old system, where it took 15 minutes for the exact total to go away?

That's just the bookkeeping end of things. It doesn't even begin to address the fact that they merged their great grocery app into their terrible everything-else app.

I understand that entropy comes for us all, but this isn't just something falling apart, this is someone actively making things worse, like a web designer working for Amazon. Stop ruining things that work just fine.
