Courier Question

I placed an order but quickly realized that I had the wrong address listed for delivery. It was too late to cancel so I contacted support and had them change the delivery address to the correct one. They quickly updated the address only for me to later find out that support never gave the courier the updated address despite it showing up for me so they delivered it to the old address. Support issued me a refund and then said something ominous about “following up with the courier to ensure it doesn’t happen again” despite it being the support agents fault, not the courier. What happens to the courier now and will it matter if I try to contact support again since it seems they still inexplicably don’t understand it was there fault for the screwup? The courier isn’t going to get fired, right?
