I am using ABC Broadband from more than a year. Plans are costly compared to other internet. Speed will be very less in the evening and during weekends, sometimes you can not even open google page. If you call customer care you will have to wait minimum 15 minutes to talk to customer support engineer.
There are other broadbands in my area which got really good plans.
Example: for 20GB, 2MBps ABC Broadband charges 782 Rs(including tax) whereas metronet charges 800 for 50GB!
