[Resolved]  Airtel — Delay in airtel fiber installation

I subscribed for an Airtel Broadband Connection(fiber) in Patna, Bihar. But the Person took installation charges from me on 26th/25th august.
When I call him all he does is give excuses and pins the issue on the technical team, saying we will get that done tomorrow.
His name is Amit kumar and his contact number is [protected].
This man, Amit kumar gave me the number of a technician saying he can't do anything anymore, the technician will. but the technician doesn't pick up any calls and when he does, he doesn't give me any time fram when he will visit my house, his name is Sammi kumar singh and his contact number is [protected].
I can't just sit at my house all day and wait for him, everyone has jobs they have to do. I need an Internet connection as soon as possible and it has caused me major inconvenience.
Please take immediate action.
