Sify cheaters!. Review on Sify Broadband Internet Connection

I am from Goa. I switched over to Sify Broadband from Dial up, since it was cheaper. At first their line was not activated and they said my LAN card was faulty! Luckily it was under warranty so the Vendor Checked it and prooved it working. After that Sify was good for some time. I took an unlimited 64Kbps package.(150MB Day limit, Night-Unlimited). I payed Rs.2000 for installation(non-refundable). Then for long time I couldn't connect due to some ''Local Connectivity problem''(error BB101) Then it worked fine(after 10 days). Now their Day speed is OK, But in the Night the speed is negligible. For 10 hours I got only 20MB downloaded! sometimes it doesn't log-in at all at night. We called up their Customer care(Chennai) but they are idiots. Don't Go for Sify, their Service is terrible So choose wisely, don't fall prey to dirty tricks. And One thing I forgot, when u complan to them they give an error no. They say at the end of the month to report all the errors and we will refund the no. of days. When we gave them the error nos. they said ''we can give only upto 3 days'' I argued with them that their service was down for more than 10 days. All the people in the buildings around me are also very angry about sify. So we don't recommend Sify!!!
