MakeMyTrip India — Not getting refund from mmt

I booked a holiday package in mmt with booking id NL[protected]. I could not completed this trip due to corona outbreak and applied for refund. They send me a link after 6 months for varification of account and to submit bank details. But Whenever I put my mobile number which I used at the time of booking a message " you are trying to access a booking, not booked by this number " is reflected every time. Even I am unable to get OTP on my mail id for varification. My mail id is [protected]@gmail.com and registered mobile no is [protected].
Plz do something in this matter. I am waiting for refund from 10 months.
