MakeMyTrip India — Refund for cancelled flight ID NN[protected]

Hello,
This complaint is regarding a flight scheduled on 30th Aug with Booking IDNN[protected]. I had cancelled the flight on 27th Aug and the amount refunded was showing to be around 24, 000 INR. But today I have gotten a mail stating the refunded amount will be Around 5, 000 INR. According to cancellation rules, if anyone cancels the flight before the flight date then the airline deducts 13100 INR. Very disappointed with the service. THis is certainly a scam. I want my money back. Please help.

Regards,
Premanshu
