My wife had an interesting issue in the UK with Amazon very recently. I order a lot from Amazon. A lot. 99% of all packages turn up same or next day no issues. My wife started ordering some things and they kept going missing. We compared addresses and they were identical. Order tracking kept showing a delivery date, then the date came and the item was just returned to warehouse. Repeat 5x times and after many 40 min phone calls she just cancelled the order for a refund. Repeat 7 or 8 times. Phoning up the Indian based call centre helped not at all. Hours wasted She tried one last time and got a call back from a manager in the UK who looked into it. After a week or was resolved. I still don't have a technical explanation, but apparently some special routing meta data had been added to that address where the package was always routed through another logistics centre or something. Total nightmare getting it sorted out
