I have been using the Australia Post Parcel Lockers which have mostly been very good.
It is like a post box but doesn't cost anything. The lockers are located near many Post Offices and when the parcel arrives I am sent a TXT message containing a six digit code to open the locker. The parcel is there for 48 hours and can be picked up anytime day or night.
Recently Australia Post had a complete outage of this system where the lockers would not open. There was (and still has been no communication from Australia Post regarding the break down). I went twice to pick up the parcel but couldn't. The first time was at night so there were no staff there. The second time was during business hours but the office was closed (staff were there) and parcel pickup is supposed to be able to ring the doorbell to pick up items but no one would answer.
The third time I rang the hotline to check if the system was working and they said it was (two days later) but now the parcel wasn't in the locker. I went into the office which was open this time and got the parcel. Each trip was twenty minutes return. This is normally convenient but it is annoying for a wasted trip. Meanwhile there was nothing from Australia Post. When I picked up the parcel the staff said nothing.
For a company whose job is communication they are extremely bad at it. I don't go to our local post office because the queue is normally ten to twenty minutes. Australia Post has no customer service ethic. They are very public service.
I am still getting emails threatening to charge for storage of the item I picked up. It is up to me to fix the problem with their system!! I have to call them to tell them I already picked up the parcel from them. FFS
They are a bunch of incompetents.
