Airtel — regarding complaint against the customer care executive supervisor

Hello sir,
I am siva, i just connected with the customer care executive about my issues at 23:19,[protected]. He can't solve my problem and he connected the call with his supervisor to me. But the way of supervisor spoke to me is really hurts and he didn't reply me for a long time while i am in call, and she spoke with some colleague instead of speak with me. I am not satisfied with the way of her speech and she shout on me and she disconnected the call while i speaking. This is not the correct way of treating the customer. I have the call records also. I want make a complaint against her legally from your side. I hope you will take a action about this complaint. My number is [protected].
And i also want to follow my complaint and the action taken by you on her. Please make the instructions to your executives about how to speak with the customers.
Thanking you,

With warm regards,
Siva.
