MakeMyTrip India — Refund incorrect

I booked andaman trip with makemytrip to travel in feb 2022 but had to reschedule to april due to covid .
I had originally paid in credit card and since i had to get it rescheduled they provided a gift card of equivalent amount and i had to pay additional money via amazon wallet as trip was more expensive this time .

On my trip starting 3rd april they cancelled few activity and provided the refund of rs 3900 again to gift card instead of amazon wallet .

Now the problem is the gift card is usable only if i book another holiday package with them and i cant even book flight or hotels with it .

I have already requested them since i paid originally in credit card and also i paid additional amount next time via amazon wallet the refund should be to my wallet at least .
I have also requested to provide it to make my trip wallet at least so I can use it .

Now the gift card is unusable and the balance will expire in few.months .
I have tried reaching out to them but they either are not reachable or give excuses to reach concerned department .
They are chating customers .
I need my refund
