Hey I'm from Sector 31, Gurgaon and I had an Airtel connection earlier but I shifted to BSNL due to lack of Customer Care support and due to the fact that they weren't changing my plans even after repeated complaints.I shifted to BSNL and all got done in a span of 3-4 days.I applied online on the BSNL site and they needed the locaion and stuff and all...Then i received a call from a BSNL executive asking for stuff like the plan and the type of modem and more stuff..He then sent the installation people the next day with the telephone system, modem and wires and all...They connected everything well, no flaws, no messy stuff.. though hey seemed to be interested in bribe but if you just ignore that and talk to them about some technical stuff that they don't know they'll just pass...they in actual don't know much technical stuff, if you want to know about the technical stuff contact the executive who had contacted you before for the connection or contact the customer care number...I had opted for a 4mbps connection unlimited plan that costs 1350 and gives 30gb fup.For a week i didn't get 4mbps but got 2mbps, I at once called them up and complained about the same.. they said it was not in their record that i had a 4mbps connection coz i was a new user... but then in 4-5 days the connection was shifted to 4mbps on its own without me complaining further...Till now after 7 months with the connection, I really haven't experienced any connectivity issues, so really don't know about their response and stuff...About modems, the executive asks you about it initially that you want a wired or a wifi modem, the wired one will cost Rs 500 and the wifi modem Rs 1000 and thats all the extra money that you need to pay...Thats all I can tell for now, any further info you're always welcome to ask... 🙂
