Airtel — Broadband not installed - Airtel

I had raised a request for new Airtel broadband connection. Ticket number is 21-[protected]. I had paid around Rs. 3000 for this and it was supposed to be installed on 15th Nov. It has been 5days now and still the broadband has not been installed. I have tried customer service and they have not helped in any way. The executive responsible for this installation process stopped replying once payment had been made. This is extremely harassing and causing major issues since we are not being able to work without internet connection.
