Asha Net — difference in charges for same net packages.

Address:

B/203, Abhilasha Apartment, Sai Nagar, Vasai Road, West., 401202

I am using internet - service provided by asha net - vasai.
I had renew my plan on 3rd august2019. Plan (10mbps speed - 15months - for 4000 + 720gst = rs.4720).

Before renewal of plan i had asked for discount from operator asha net. They said it is not possible for them to give below rs.4000 + 18% gst.
I asked them for rs.3500 in cash. Which they denied to accept the offer saying it is not affordable for hem to give in rs.3500/-
So i buy it in rs.4720 including gst.

After few days i. E on 09.08.2019 one of my friend using asha net got the renewal of the same plan and package for rs.3500 (In cash).

For this difference in charges i made complaint to asha net; on which i got reply on mail from owner's daughter darshan verma stating that you ask for discount every year so this time i decided not to give you discount.

This is how asha net is doing partiality;
I am using asha net services from 4 years.
Just asking for discount every year is not a crime according to me.
But darshan verma gave me same plan for higher price to satisfy her ego on me.

I request you to kindly look into the matter and give proper solution for this...
I have all records in my mail / whatsapp... If required...
