BSNL — Pathetic Service And Outages

I have been using BSNL for past year 3 years or so. I was on BSNL DSL Connection which has been upgraded to BSNL Fiber on April Of This Year. In This Time Period I have been provided with one of the worst internet service for the time. I am currently On Fiber Basic Plus Plan which comes for 599 + GST and 60mbps speed until 3.3TB . I am getting constant slow speeds, packet loss, ping spikes every month. BSNL officials aren't responding to my complaints even though I have complained every month the same thing is happening next month. I also don't have any other connection availability except BSNL in my area so that's the only way i can go for. I am not getting the worth of my money using BSNL FTTH and FTTH is supposed to way stable and faster than DSL Connections.
Today December 15 2021 I am facing slow internet speeds, packet loss of about 30%.This needs to be fixed.
When I Told BSNL that i am getting packet loss they doesn't seem to understand what I am talking about so the technicians aren't familiar with the concept of packe loss and ping. According to them i[censored] are getting ur internet speed everything is alright. BSNL has been hell for me.
