I have had a lot of issues with UPS.
Several times they left expensive items by the mailbox which is secluded from view and about 1000 ft down hill. Then they started dropping them at the lower building. Then they reported attempted deliveries saying no one was here which was absolute BS and my security systems cameras proved they didn't even come p the driveway.
Somehow I eventually got lucky and received the number of a lady at the local hub. The last time she said they have really clamped down on the drivers backing up due to accidents. I said well it hasn't been an issue for 25+ years. She pulled up an aerial view of my property and siad it would be addressed I've had to call her a few times but the last 3 months or so have been good. Driver seemed a bit PO'd but Tough sh-t
