Airtel — broadband activation issue

Address:

19th Main, Indiranagar, Bangalore

I have requested a broadband connection for my home address on 3rd april, 2020 and they promised to install by 7 anyhow. Now after more than 10 days they are not activating it and also there is no way to get my money back.

Customer id : [protected]

Please help me to get my money back so i can choose another vendor, there is no more trust left with airtel.
