when ever you have trouble call sify customer care and get a complaint number every time and once the problem is sorted ask them to compensate you for that much time.. They are genrally ok with compensations. I do it all the time and never had a problem with them regarding duration of time or anything.If some one makes a fuss just shout over the phone and scream and do whatever you can... and you will get what you want.. this is India
