Meanwhile, your local employee having Mobile No. ********** made contact with me and has given assurance that Airtel Xstream Broadband will give me require speed. Later on he has visited my house with various plans. Accordingly I have selected *** Mbps plan and has paid amount of Rs.****/- for three month through the link sent by Airtel on text message on yesterday.
Later on I have received text message from Airtel and it was informed that appointment is confirmed and Airtel Engineer will visit my place at morning for installation process. Your engineer visited in afternoon and has stated that, there is no box in my area and therefore you cannot give me broadband connection.
