Airtel — delay in new airtel broadband connection and very poor customer service

Dear sir
I wish to complain about my painful worst ever experience with airtel broadband!!!
I had applied for a new broadband connection with airtel through online portal on 21-july-2017 from the area virugambakkam, chennai - 600092. My order id (Crf) is : tnpg078744. I had provided my details online for the new connection and i was contacted by a csr on the same day regarding my interest in airtel 's broadband plans and connection. An executive came to my home and collected all my relevant information and documents. I was told to pay the activation fee for which i chose to pay three months rental in advance for waiving off the activation fee. I paid an amount of rs. 4598 immediately in front of the executive and gave him the payment transaction id for specifying in the application form.
After he left, till date i am struggling to know the status of my internet connection. I called the call center so many times and finally yesterday they told me that my application is in rejection status because email id was not mentioned in the form. I had to call them multiple times only to know that my application is in rejected status. Before paying the amount, i was contacted numerous times by the csr but to know the status, i had to follow up many times. They did not even had the courtesy to call me and convey that some detail is missing. They are blaming some other departments and trying to escape my query. Till date i have not been contacted by anybody about my connection. Its only me who is following up constantly for my connection. Everytime i call the customer care, they keep telling me that within 24 hours an executive will call you, but i have not received any calls so far!!
This is my worst ever experience with airtel. I did not even imagine that the service will be of such low quality and the customer care will be so much lethargic about a consumer's connection request. I feel that my money is lost because the response shown to me so far is so bad that i feel airtel is not in a position to provide the fair service i deserve for the money i paid. Kindly help me in this regard and please create awareness in public about the poor service provided by airtel. Please help me sir.
