Flipkart — Refund of ticket price

Hi,

I booked a round trip from Mumbai to New Delhi (27th May to June 05, 2022) from Flipkart with FLYNEW offer with which i received Rs 2000 discount (Trip id:[protected]. I travelled from Mumbai to New Delhi. However due to negligence of airline staff, i was not able to board the flight from New Delhi to Mumbai . When i raised the complaint later on, the airline company offered me full refund and asked me to contact my booking agent. When i contacted Flipkart. they issued me refund after deducting Rs 2000 which was the discount i was offered on round trip. As the discount was on the round trip and the cancellation was only of one leg of the trip, they should have deducted only Rs 1000 instead of Rs 2000. incidentally, the customer care initially told me that only Rs 1000 would be deducted. I want flipkart to refund me additional Rs 1000 as the cancellation was partial.
