After waiting in all day for UPS to deliver my 6, with them telling me multiple times that it would be delivered today, at 6:13pm, the tracking gets updated with:
"Delivery will be delayed by one business day."
After talking to them, apparently they just had so many to deliver they couldn't manage to deliver mine, and didn't think it'd be good to check that/tell me in advance. The only thing they can do is ask me to wait in all day tomorrow as well, because hey, today went so well.
Incandescent with rage, doesn't quite cover it...
