Change billing cycle from Today: If you want to change your account billing cycle and want to start it from the current date, then you have to select the option “Change billing cycle from today”.
After selecting this option System will automatically add Reconnection fee charge (Rs. 50), which is mandatory to start the billing cycle from current date.
Keep old billing cycle: If you want to start your account billing cycle from the same day where it was left earlier (Date of Deactivation) then you can select “Keep old billing cycle”. In this case, the billing will start from the old date (Last expiry date) no matter when you make the payment.
