Ecom Express — About an agent in ecom express using bad words

Address:

Tadepalligudem

I was about to receive my ajio order today. An agent called me today early in the morning around 6:30 and asked for my address, i told him the address.
I again called him by 9 in the morning and asked him when my package will be delivered, he said it will be delivered after 12 in the afternoon. Then I asked him why he called me early morning if he is delivering after 12. He used bad words and told me not to tell him what he has to do in a high voice.
