Mhada — Refund not received

Website:

lottery.mhada.gov.in

We had registered for MHADA lottery 2021 and paid it's registration fees amounting to 25000. We didn't win the lottery, and hence as mentioned on their website, our money was supposed to be refunded to us till 22nd Oct, but we still haven't received the refund yet.
Kindly look into this matter.
