[Resolved]  Air India Express — Instead of refunding when I cancelled the flight making it rescheduled by default

I have made a booking initially for airasia flight from Bangalore to Bhubaneswar on 17th Feb with PNR Q1VWHC but due to some reason I have to postpone my travel to 19th Feb.
Since I got better offer on Makemytrip I made a fresh booking with PNR E9NLKH for 19th Feb and cancelled the existing booking with PNR Q1VWHC but somehow on your site it shows I have rescheduled this Q1VWHC PNR and asking me to pay Rs.3000 instead of refunding me the amount after deducting the cancellation fee.
I contacted the customer support and useless TIA also and everyone mentioned we can not help with it as there is due amount of Rs.3000 need to be paid.
Requesting a quicker and faster resolution from your side. Customer care should have at least some common sense to check it as why one person will book same flight same day twice.
