Airtel India — No internet service for 10+ days

Sir, I'm writing this to inform you that my Airtel broadband/internet connection is not working since 23rd May. It's been more than 10 days and I'm getting no proper response from anyone. I have sent numerous emails and called CS care, no resolution. My entire work is dependent on internet connection as I'm working from home since pandemic. Every representative who visits my home says issue will get resolved in next half hour but nothing.

It's been a horrible week at my work as all my deliverables are impacted due to this. It's really frustrating for me as TN is in lockdown and I cannot visit my relatives house for this..

What has to be done to get this resolved as my pressure is mounting high due to my workload and I'm getting irritated to the core. M in ground floor so Mobil data is also not available.
