OLD RULE - downgrade was possible once in a calendar month and upgrade was possible as many as u can.
NEW RULE - downgrade is not possible within or before 30 days. now one can downgrade the package only after 30 days.
TRICK HOW TO DOWNGRADE UR PACKAGE WITHIN 30 DAYS ALSO
take a la carte package of 171 rs.
e.g. - if I have 275 wala package and I want to upgrade to sports package bcoz of indian matches but as per the new rule after upgrade, I cannot downgrade before 30 days.
but if u will select a la carte packages then it will be done.
now take a la carte package and the package will be changed within 48 hrs. after the package changes to ala carte package then again u can upgrade ur base pack.
