What i need to do if i didn't get the information from rti?

You can do many things like -

(1) Keep quiet and do nothing.

(2) If more than 30 days is over from the date of your request, then you may appeal to the first appellate authority.

(3) Or if you want to give one more chance to the Public Information Officer, then you may send a reminder.
