MakeMyTrip India — Cancelled ticket Refund not credited in my account

Ahmedabad

I had booked flight ticket to travel from Ahmedabad to kolkata on date 22 june 2020 and return on 16 july 2020. Later return flight was cancelled by Indigo Airlines. Indigo refunded the ticket amount 4591 to Make my Trip but Make My Trip did not credited that amount in my wallet. When i am checking in my MMT account it is showing refund processed.
