Absolutely horrible broadband service from Alliance Broadband

Since Amphan cyclone happened in kolkata the internet service by Alliance broadband has become absolutely pathetic. Since last 2 months almost every single day frequent disconnection issues are happening. Due to which i am unable to attend meetings and complete daily tasks. As most of us are doing work from home so this is raising a big question on our job security. Even after raising numerous complaints nothing really changed. Every time they said there is a fault in the line which they are fixing. But nothing seems to be fixed at all.
