Was home all day, never rang, never knocked, but put a " Sorry we missed you card in the mailbox". Made me go to the post office to pick it up.
I had 2 items in the delivery depot literally 2 minutes down the road, but they just dropped off 1. Also told me that 1 would be dropped off yesterday after 1pm, checked the tracker this morning said " unsuccessful delivery" that was never even attempted.
