I think that OZ Post went to crap when they started using contractors to do deliveries. It would appear that anyone who has a suitable vehicle can apply to deliver parcels for them nowadays, I've seen adverts to that effect ... I have also seen numerous non descript vehicles with non descript drivers picking up parcels ( bulk ) from our local post office for distribution. They are obviously not on a salary from OZ Post so probably cheaper alternative ... who cares about the customers seems to be the ethic these days. It's all about the bottom line.
Only today we had a card left in our mail box to go and pick up a parcel from the post office .... supposedly the person rang our bell and no answer .... actually nobody rang our bell it was probably raining heavily at the time and it was easier to drop a card in the box than do the job properly. This isn't the first time it has happened either.
