Den Networks — no connectivity issues

Hi i took this connection around a month ago on 2nd march for 3 months and paid 2124. Though it was slow than the speed promised we (I and my husband) didn't mind as after coming from office we barely used it for video calling with family and friends or normal surfing.. Though we faced frequent disconnection we just ignored as we barely used as i said earlier. But due to covid 19 we both got to work from home when it turned into nightmare as from 21st march the line went completely dead. We complained and the technician came did some changes in the frequency and it worked for hardly 30 mins. The technician came on 23rd so when we called again he said he won't be able to come to check due to curfew. I repeatedly requested him to check from his end as the connection is fluctuating. If the issue had been from my end i would not be getting any connection. But he just disconnected the call and from that day onwards i am just able to use it hardly for 30 mins max everyday. I have lost complete faith in this connection i am just waiting for the situation to be bit stable and then first thing i will be doing is taking a different connection.
This connection has been just a nightmare for me and my husband. Due to this connection we both had to face hardship in office. Neither the nodal officer nor the technician is helping us in resolving the issue. We just want our money back and some action against them.
