Airtel - Cheating money for no feasibility of internet connection

I applied for Airtel Xtream Fiber Internet Broadband connection on *th October **** and i submitted all the document and as well paid amount of Rs.**** (* months advance rental pack).

Before paying the money i asked multiple times to supporting executive he also confirmed feasibility.

But as of now they are not given the connection to me. When ever I called them the technical person responding me in rude manner "It will take more days to fix the problem, if you have urgent talk to zonal manager i will given his number".

This is the egoist problem between two team. why making suffering customer.

Airtel is not capable to handle the customer, poor customer care
