I recently ordered a small appliance from Walmart and chose the option for next-day delivery, which turns out to mean delivered from a local Walmart store, and Walmart subcontracts that from-store delivery to DoorDash and other companies.
Later the same day (not next day), I got a notification that the package had been delivered, left on the porch. That seemed strange, since I was at home sitting on that porch when they said the delivery was made. They provided a photo "showing where the package was left" -- but it was in fact no such thing, it was just a stock photo of the item from the Walmart website. I walked around the neighborhood, thinking maybe they left it at the wrong address, but no luck.
Finally, I called Walmart and a CSR looked it up and said, "Oh, that's being delivered by DoorDash. They sometimes just say they delivered things even though they haven't. You'll probably get your package tomorrow."
I asked him if Walmart was okay with their delivery service lying to customers, and he said, yes, Walmart is totally fine with it.
I did not get my package the next day. Or ever. After three days, Walmart refunded the order.
The moral of this story is that DoorDash is a company of liars. Don't trust them. I hope the company dies.
