Made a complaint and postie confronted me at my home

I made a complaint cause it’s been a few times this week that my parcels were not delivered. I work from home and have a decently loud door bell. One missed parcel I could understand but after two more, I was pretty annoyed. After my complaint, the postie banged on my door and confronted me about the complaint and was pretty aggressive that I should be checking my cameras before complaining as he was adamant he knocked. He was accusing me to putting a black mark on his name. He was pretty intimidating. Is this how auspost handles complaints? I feel like my privacy was breached and that this shouldn’t have happened. Is this standard auspost process to have postie show up at your door?

Updates: Thank you for all the support and suggestions. It seems that isn’t standard procedure for them to confront people.

Answering some questions here: 1. was he a courier: This is a good question, he didn’t have the red postie van, but he did say that this was his common route and that his manager got the complaint and told him to come talk to me directly. So as some suspect, he is probably a third party working on behalf of Auspost. Another weird thing was that he was saying that he was away last week (week starting 24 Feb) so it can’t be him not delivering so why did I complained about him. I just moved in on 2nd March and didn’t complain about parcels not being delivered before I moved in. I did have to collect it at the auspost distribution centre. He also never left one of those red and white cards - but I don’t think this is standard anymore?

  1. Footage: Yes I did check the footage for the time period that they said they attempted delivery. There was no-one that showed up at that time period. Also, I checked the other 2 missed deliveries as well and there was no one. Hence the complaint. Everyone is doing it tough, so I’m not about trying to ruin anyone’s livelihood. Also, my complaint was very generic. It was like hey, I’ve had 3 missed parcels this week, I wfh so it’s very hard to miss. Could you please ensure whoever is delivering ring the door bell.

    1. Complain again: I’m a little asian lady. I’m a bit reluctant to report again as he was pretty aggressive. He demanded I withdraw my complaint when he confronted me. I did tell him that I checked the footage and there is that the footage showed no-one at that time period at my door. He said he didn’t care and I need to withdraw my complaint as he said he knocked. I’ll mull it over this weekend to see what I should do.
  2. Why not use a parcel locker or leave on a safe place: I don’t own a car, so parcel lockers are out. I’m not going to pay for an uber to go collect my large parcels. When I’ve told them to leave in a safe place, I’ve had instances in the past where the parcel wasn’t there and I was told I had waived my rights by saying they could leave it. I am aware that this doesn’t happen all the time, but I’m not risking it for a $500 parcel.
