Digitlogics — Misbehavior Courier man, bad service

I want to complaint about Nibuchour Kotdwar Uttarakhand 246149 courier services. The wrost services I ever felt. My company sent a Desktop for me and this courier branch told me to take this from their office as they don't want to deliver this. Another I bought some books from Delhi and they sent a courier to this office but again when I call them they told me that you have to pick up it from their office and when I said to them why they don't want to deliver this then they told me they will deliver tomorrow. I am doing a night shift till 7AM so when they called me at 10AM I was unable to pick up the call but I called back him at 11AM he was talking very rudely and told me that now he will not deliver my courier to my house. Very bad courier services and now on I don't want anyone to courier me anything from this service I prefer Amazon and Flipkart rather than this service because atleast they understand customer situation and also talked to the customer with much appreciated way. The courier guy called me again and asked me to come in another location to pick up the courier at that time only me and my mother were in home so I politely said to him that neither my mother nor me are able to come that location so after that he came to my house but he was talking very ridiculously to my mother and told her 'you also came to the location which I was told to your daughter'. He was talking very insolent with my mother. I am writing this email but not sure if your services could address this complaint.
