So far I have experience of using following Internet Service Providers at Delhi (pin 110014) (list in the order of switching from one ISP to another):Sify BroadbandWorldPhoneTikonaSpectranetCandor InfosolutionsSify Broadband was good. But it did not have high speed plans then (5 years back). Presently, Sify does not have network in my area.Worldphone has similar problems. Connectivity used to be lost for long periods of time.Worst experience I ever had was with Tikona Wibro. That company installed me the connection but never provided the actual internet service. Reason given: "Hamare access point ki capacity khatam ho gayi hai. Customers zyada ho rahe hain." Had to switch to Spectranet due to the nightmares from Tikona.Spectranet was the best ISP I ever used. The only drawback is that you cannot pay your bills online. You have to depend on "Cable Wala" for subscription recharges, etc. I used Spectranet smoothly without hassles for last 3 years.But the cable operators are not honest. He took my monthly payment of January 2012 for Spectranet and switched my connection to Candor Infosolutions ("Ber sarai" based Airtel reseller). Cable operator says he has stopped providing Spectranet now.The Tikona-like troubles have again started with Candor. I'm losing the connectivity frequently. Cannot even download 100 MB file in 2 hours. Further, Candor does not even show the tariff plans openly, not even in website. Candor's CCE says in phone that "Tariffs are company secrets"!!! Candor is charging me 1200 Rs per month for 768 kbps connection!!!I don't know what to do in this situation because the irony is that we have only 4 ISP's in Delhi's 110014 area: Reliance Wireline (does not respond to connection requests), MTNL (sarkari red-taping), and Candor.
