I don't know any other delivery service that so consistently feeds wrong information by over promising when no one asked it to and then under-delivering even the initial estimate.
The Friday before the Monday which they were scheduled to deliver, I got a delivery exception saying that it was unable to be delivered according to my instructions and that nobody was home. I WAS home, though I was not notified they were coming, and I can't think of a scenario which "inside or outside the gate" does not cover.
On Monday, Tuesday, Wednesday, and Thursday they updated to say it was 'out for delivery', each time updating in the evening to say the following day after they failed to return to my house. It was finally delivered 1 hour after I left for the airport.
