I am using hathway 512 kbps unlimited Rs 550 plan speed is good enough to browse the web site , download the contents.. only exception is watching online video .It will take sometime to stream .People who likes to watch youtube videos this not the connection. But when you are going for 512 kbps speed you cant expect a uninterrupted youtube video.
Customer service is good. sometimes you will face connection problem but usually gets rectified in 2 to 3 hours...
One thing I really dont like is paying the net bill in advance for a month. After reading others comment I came to know about their Fair usage policy ..Its their hidden policy really s**ks below is the link https://hathway.com/brodband/prod_broadband_fair_usage_policy.asp
