MakeMyTrip India — Refund not getting transfer to original payment mode

Address:

MakeMyTrip India Pvt. Ltd., DLF Building No. 5 Tower B DLF Cyber City, DLF Phase 2 Sector 25, Gurugram, Haryana 122002, India

I have Cancelled my flight booking and that refund amount is credited to my MakeMyTrip wallet. Now that amount is not getting transferred to original payment mode as MMT is giving error while transferring the amount. Even customer care numbers are on IVRs and they are not replying to the emails. How can I reach to them to raise my concern.
I want the amount to be in my original payment mode or in bank account.
