Airtel — airtel broadband not working and no help from customer support

Dear Airtel,
This is my second complaint today, as you are not working as my broadband and I am regularly paying to you.
All your customer care numbers are busy and not working.
So, no help from any side.

Please stop robbing my money.

Airtel is selling broadband plans in Noida, Sector 82 without any infrastructure or support.
Even they don't have adequate customer care staff to support your queries or work on service request.
While they would talk about 150 GB, 40 mbps - scenario is that you won't go far beyond the google home page, it's haed to even open their app using their broadband connection.
I have been waiting for their response for no effect.
