Airtel — Installation of Airtel Fiber pending for 14+days

I paid the complete amount of Rs.2829 on 04/06/2021. I was promised that the connection will be installed within 72 hours but instead of this whenever I try to contact Airtel Customer Care, they put me on Hold for long duration and tell me to wait for 24 hours without even providing a valid reason. The company is daily installing new connections in my area and even one flat in my own building has an Airtel connection so there is not even the problem of reach. I am currently pursuing my BTech degree and my studies are getting hampered. I have contacted Airtel customer care almost 10 times and always they say “kl ho jaega sir” without a reason being provided. It’s a Violation of the Right to Information under the Consumer Protection Act 1986.
