This surcharges is Charged 1st time for fuel payment otherwise, before this i never charged.
Update-
As customer care said, this is charged by Merchent or acquiring bank (not by jupiter).
(Swipe machine was from ICICI Bank)
But still confused about, how can i know during payment that i have also need to pay extra surcharges?
And how can i avoid? 
Thank You all for your reply.
