Airtel — wifi connection and customer care behaviour

Address:

Bangalore, Karnataka, 560037

I am a new airtel customer. I book the wifi connection on online (Airtel.in).
When i book the connection 1 guy came and tool documents and money and he said next day only he will provide me the wifi connection. But now almost after 3 days they did not provide me the wifi connection yet. I try to call customer care they are also not ready to take the complain. I book the connection from [protected] number. And my payment txn id:[protected]. Cef no: 80180259. I am really disappointed with this kind of thing. I will never choose airtel again.
