reilance jio - Jio Giga Fiber Installation getting delayed.

The most pathetic and fraud service we have got from Reliance Jio. First fraud they did when we were speaking to them regarding Jio Giga Fiber Internet. Salesman of Reliance promised us that they would take maximum of * days to install it and not more than that. I have taken a connection on **th of July, They have given the time of * days for the installation. but it was not fulfilled as said. I had done the all possible followups with salesperson, customer care team. and now There is no response from your sales team, nor did they pick up my phone.

I have spoken to my Customer Support assistants and all of them say the same thing that "Your installation is delayed due to some unavoidable condition. We have initiated a complain regarding that. You'll be getting an SMS within **hrs". But till now I never received any kind of SMS nor Call regarding the issue.
It is not working and we have filed a complaint multiple times about it. How is this possible every time? They have been fooling us since very long. Would really appreciate consumer court’s help in this. They are fooling us big time. How can such a big organisation work like this – we fail to understand.
