Airtel broadband connection

I have requested for the new airtel braodband connection 2 weeks ago and the executive name Chiti Babu (Sr.Officer - Sales)Phone No 9866011107 - Hyderanad. He has told me that i will be getting in 2 days.
He has taken the documents and Rs 500 for installation.
After that day he never picks the call nor i have got the connection.
It looks that this executive has cheated me.
I am really diappointed with the Airtel. I suggest to everybody that pls dont take the call from this person
