I have had had broadband for last 5 years fron Dishnet in Chennai

Hi,
I have had had broadband for last 5 years fron Dishnet in Chennai 128 to 512kbps.They were great, always on.After Tata Indicom’s takepver also it was fine although levels of service were slowly deteriorating.
Last 10 days their connection is off-all complaints to no avail. No link
I thought of taking Sify but seeing all these comments above I will try something else.
Thanks you all.
I have Airtel last 2 years and they are excellent although initially they were overbilling and you have to fight every month. Now they don’t overbill!!.
I have a business where I cannot afford not to have internet even for 2-3 hours
Thanks
Narayan
