Personally, I have very lil faith and respect for any Goverernment Enterprise(BSNL, Railways, Traffic Police etc.)
Not that SIFY is too good either, but ive had no reason to regret in the last 3years that ive been a customer of Sify.
Prolly, someone who gets the same charge can help you, Janitha.
Regards.
