MakeMyTrip India — Unsuccessful flight trip amount not refunded

Very disappointed customer service as we have booked a flight on 7 July 2022,
But due to some technical issues ticket was initially shown as unsuccessful in MMT aap.

Initially on app it was shown that payment will be refunded after 2-3 days, we have also raised query after 4-5 days as it is not refunded till now

Tried via call but no response.
Money not refunded yet.
