Delhivery — Rude behaviour of delivery agent

Coming to the first incident, I have ordered something from a website which delivers through delhivery and one day a delhivery agent called me and asked me the delivery code before appearing to me! When I asked why he asked the code before delivery then he said he had a rush to home so he is in hurry after he get my delivery code through call he will deliver it to me. But how can I trust him! I denied to give that and after 1 hour he came and gave the package.

The second incident happened just today in the afternoon. I have requested a return from an website. Today morning I got a message that Delhivery will pickup the return. In the afternoon the agent called me and asked the location in spite of the address is given already. I told him the direction to the nearest landmark and told to call me after reaching that. After some time he again called me that he didn't find the landmark, I told him the direction again. After that he again called me, then I told him the exact direction to my home but he shouted at me why I am not at the landmark which is very absurd. I told him repeatedly that it is the landmark that doesn't mean I live there and you have my address you can find it easily. But he didn't listen to me and shouted repeatedly. Then I also got angry and then told him that you have my address you come to me I will not give you further information. In less than 1 minute he entered in my house like a hooligan. I sent my husband to talk to him as I didn't felt safe to talk to him. My husband took the package which I have to return and asked for some confirmation, so he rudely told him I don't know anything...I am from delhivery thats it, now give the package. My husband denies to give that which is quite normal. There is a valuable thing in the package how could we trust him after his behaviour and even he is not confirming anything about the return. So after we denied to give him the package he kept shouting throughout the road like he had done a favour to find our house. What kind of attitude is this!
