Airtel - Airtel — airtel broadband online fraud-aug-2018

I want to bring to your attention an online fraud that has been done by airtel and its representative. I applied for airtel broadband connection online and received a call from airtel representative name "Anandan j" and he asked me send documents aadhar, pan and rental agreement as proof of address and photo id proof via watsapp.
I send him the document and he gave me a CAF number to make online payment of **** rs toward new connection. which he said this plan is for * months with free router and installation charges.
When i try to login to airtel portal online
http://www.airtel.in/payonline/?oa
it was giving some error and so i called him back saying it is not working.
He provided me with Bank of India a/c number and asked me transfer money. I transferred money.
when i called him for setting up connection he said it will take *-* working days and due to some doubt called airtel customer care and now they were telling service is not available in my area.
Now that representative is not picking up the phone and i have not got the broadband connection.
when i try to call the representative he is not ready to refund my money back and not answering my calls.
NOTE: For Airtel this is a bad remarks which makes people not to trust in future. people like this will survive for few days but soon going perish.
