MakeMyTrip India — Amount not refunded for unsuccessful booking

I have recently booked a train ticket from Gudivaada junction to Anantapur Railway station on 24th April, 2023. The booking was unsuccesful but I did not get my refund back even though the expected time limit is completed. When I visited the customer support portal, it is showing that the amount was credited. Then I opted for create ticket option to get the status, it is also not working showing that something is wrong.
