MakeMyTrip India — iam complaining about changing the status of flight ticket to refunded from open status

I had booked a ticket from banglore to paris on feb 26th 2018, however since my visa was rejected i had called makemytrip and asked them to keep the status for the ticket as open they agreed and did so, but now when i want to rebbok the ticket they say the ticket is already refunded and are lying that ghe airlines dont have that policy but when i crossed checked with the airlines they said that they can keep the tickets open for atleat a year from the date of issue.
