Airtel — new broadband connection scam

Address:

Gurgaon, Haryana, 122002

Is this common in airtel to take money from customers ensuring they will provide them with a broadband connection the very next day and then start blocking their calls immediately. I called airtel operator like dozens of times after i paid them advance for internet connection. I am not provided with any sort of connection. I am thoroughly disappointed by airtel's sloppy services right now. I have a duplicated of customer enrollment form with cef no 12442513. I paid the operator cash of rs 500 and an online transaction of rs 500 with ref no 21945150 on 19th jan 2018. Here are the contact details of the operator that i contacted:

Earlier on, he assured me that i will be provided connection the very next day. He answered 1 or 2 of my calls and gave me the contact no of another person saying, you can contact this guy, he is the engineer and he might be a busy at the moment but he will soon deploy connection at your place. His contact number is [protected]. Is airtel a service company or a scam company. Why am i not getting reponse from the airtel team? Is this how you treat your customers?
