I have a question about parcel deliveries.?

I am 17 and a female. I usually help my bro take in parcels when he’s at work and no ones available. I heard a knock.

I checked to see who from the window and there’s a guy with parcels + a van with the logo. Therefore, I open the door a tiny little bit. Enough so he can see me but not enough for me to fit through the door gap. He asked me to sign my name for both packages on the phone. So I did. One box is small and one is fairly big.

Giving me the small box I put it on the sofa 2 feet away from me ready to get the other box. Instead of asking he pushed open the door and walked into my house to put it in. I understand he was trying to be nice and help me out but I didn’t ask him to come in and I made it very clear with my door being almost closed. I found it very rude and I was very shocked to see him push open my door and walk in with his shoes without asking me first for permission.

I’m not purposely trying to get him in trouble. My question, is it company policy to walk in someone’s house to place a parcel down? Is it normal for them to walk in without asking? I’ve never had a big parcel sent to me before so I wouldn’t know if that’s normal or not. Should I email the company to talk to their employees. No trouble I would just like them to know it’s not ok to open your door and walk in without asking. Should I let the manager know or is it not worth it? I know I didn’t tell him not to come in but I didn’t tell him to come in either.
