Cheapticket.in / Airtickets India — Deduction amount unethical

Refund of 17k, due to Airline cancellation, amount deduction break up had transaction fees attached( refund does not levy transaction 2%)
On a refund of 17k they charged 733 Rs, saying that charge will be 36k round trip whereas one way refund amount is 17k
After speaking with customer care Rahul Kapoor, the transaction amount 17k but the transaction fees is on 36k!!
FYI refund should not have refund fees,
Service fees amount not disclosed in the tickets sent ..
