I live in Canberra and receive on average one parcel per week. In the past six months I have had repeated problems with parcel delivery, with non-delivery cards being left when I have been home. I have also paid for parcels to be delivered on specific days and had them delivered on a different day. If it was delivered after the agreed time it would potentially be understandable, but it has always been delivered the previous day. Luckily I have been home on some of these days.
My main difficulty, other than the frustration, is that I have a disability. I use a wheelchair, can't drive and live on my own. I buy online to avoid having to carry large parcels myself. Having to collect them from the PO when there is very little capacity to carry medium or large parcels is very difficult. When I have paid, effectively twice, for delivery to happpen when I am home only for it to be ignored seems a breach of service standards.
My local PO has seemed frustrated when I've mentioned the problems, but I know there is nothing they can do about it. They don't know what they are going to be able to do when a parcel that is simply impossible for me to collect is either "not deliverable" when I am home or delivered on a different day to that arranged (paid) for and I am not home.
Hopefully things will improve - or at least I will continue to be lucky that so far the very large parcels have been succesfully delivered even if not when I expected/paid for them to be delivered.
