Friends height of all non professionalism is here.They are worst ISP of India.
Most of the times services are out and that too not for an hour or two it may take entire week or even 15 days to resume.Blilling is fraud they are lyers and they should be thrown out of market.
If you are planning to go for a broadband ISP never think of them.better to pay for data even if it is 2G it will be better. They are fast but not reliable even for a day.
