Walmart seems to ONLY have a “technical issue” when it comes to requesting a refund. All other areas of the website work perfectly fine!
Any time saved by ordering online and picking up the order has vanished chasing customer support people to fix something that would have taken a few seconds through their website.
If you have a Walmart card, there's a similar annoyance with the Capital One app on my phone. The screen to pay your bill scrolls up and down just fine, so you can scroll down to pay. The screen to redeem your collected points for cash back? Yeah, no. The screen doesn't scroll, so I can't get far enough down to swipe the submit widget.
