Alliance — frequent net disconnection

Address: P-31 Nani Gopal Roychowdhury Avenue, Phillips, Kolkata, Kolkata, West Bengal, 700014

Internet connection gets disconnected on daily basis and it gets solved after 4 to 5 hours. I have asked help from local operators but they cannot stop that from happening. I have lodged numerous service tickets in android app but that too cannot provide any permanent solution.
It feels very annoying and cheated for paying for the whole month and everyday using jio mobile wifi.

I havent faced a problem like this in my 10 years of service from alliance until last couple of months. Please provide me a solution.
