No it charges you and it won't show up on simpl. But check the transactions tab in your card account. These guys didn't even warn me and i got charged 215 rupees.
The customer care was absolutely unhelpful when I told them how can you charge me without showing the fee breakup. I think this was day 1 of their charging. I paid on the 18th of June.
Cancelled my account with them the very next day. Good riddance
