Better go with Delta-net cable operator.Been using bbnl connection from them since 3-4 months and only downtime was for a day when there was some issue with cable. I have used Airtel for 4-5 years and I think this is better than Airtel with hardly any downtime.If u take the BBNL connection from delta-net, there will be no FUP.Speed is around 9 Mbps, not much fluctuations. In torrents the normal speed is around 900-1000 KBPS for a good torrent. If you use IDM for downloads, u will get close to 10mbps.Their CC is really good, typically 1-2 hrs. I have been using internet from this cable operator since 2 years+, and it is the same time for resolution. Delta-net telephone no is 080-23531515
