Believe me, I've argued with UPS on the phone when I was up to my 3rd delivery attempt. They don't schedule deliveries. Told them I'll be home until 1pm, put a note on my door. Just got delivery notices for 4pm-6. Doesn't matter. My area of town must be last on their route. I just pick it up as I'd rather not wait.
I've tried everything, they just deliver between 4-6pm and whether I list it on the order for AM delivery/my door/on the phone, it doesn't work. Only when I'm at work, it's being delivered.
Drivers don't care if it goes back to the sender, less work for them.
I picked up the last 2 just to save myself the hassle, at the actual sorting plant-5min drive from my house. I pick up and order large quantities so I don't have to waste too much of my gas.
When purchasing from the states, if the seller insists on UPS, I don't order. They charge brokerage fees...
