Wish Net — poor connectivity total unreliable service provider

I am using wishnet internet connection in h. B. Town sodepur, kolkata - 700110. I have been using this connection for last 4 years and the common problem since we take the connection is instability. I have to call many a times to customer care then those guys will pick up and just listen without giving any permanent solutions. We are using through a cable operator mr. Benu / mrs. Rumu and these people don't allow us to take other connections. After amphan cyclone things went to the worse. I am working from home and connections was not there for 7 days. On the 8th day when connections came its fluctuating. I tried calling them emailing them no urge to solve the issue permanently. How long i have to tell my office regarding internet issue even they are questioning me?

They don't allow to talk to senior engineers when asked for it.

We are paying huge amount on a monthly basis is wishnet going to pay back for the 7 days when internet connections was not there.
