Respected Sir,

One of my college friend has been lately receiving calls and messages from an Airtel number.She(my friend) is being constantly harassed by cheap comments from the caller who also happens to a girl.
She( my friend ) is extremely scared to tell anyone about this.
The number of the caller is "[protected]".
I request the concerned authorities to please find out details like name and address of this caller and email me at [protected]@gmail.com and also take necessary action in this regard.

Yours sincerely
