Shree Maruti Courier Service — Complaint about the delivery guy

Hi, recently I've ordered fe products from a brand in Mumbai. The delivery guy contacted me and said he is at the location. When I asked for which location, he said " you don't know you're location? ". I told him I have house in Bangalore as well as chennai. So wanted to know from which location you're calling?. This guy told me " if you you're from Bangalore then speak only Bangalore language '. This is such non sense. I really don't know What bothers him. It is my wish as to which language I'm speaking. Who's he to tell me that? Also haven't received my parcel yet. Tried calling him again and again but he's not picking the call . Want to complaint about his rubbish way of approach.
