Happyeasygo.com - NO Refund of Convenience fees Subsidiary Product fees

I had booked a flight ticket with AIr Asia using Happyeasygo site for Bhubaneshwar to Delhi for **th January ****.
Sometime back I received a message from the airline that the flight has been canceled and I am eligible for a full refund. When I called up your customer care of Happyeasygo (I have made * calls, and each time the call has been disconnected from their side during the conversation). I was told that I will get the refund deducting Rs. *** Happyeasygo convenience fee and the subsidiary product cancellation protection of Rs. *** that I had bought. What I fail to understand when an airline cancels the flight why I have to pay these fees. The logic they are giving is we haven't cancelled the flight so why we will not charge the fees.
