Fam App Mobile Number Change Request Without Old SIM Access

I am a user of the Fam app from Bangalore, India. My Fam account is registered with the mobile number 91489524**, but I no longer have access to this SIM card. I contacted Fam customer support and requested that my registered mobile number be updated using my Aadhaar details, since I cannot receive OTPs on the old number. Despite this, my number has still not been updated and I am unable to access or use my account properly. I kindly request that my Fam account mobile number be changed from 91489524** to 70190082** through Aadhaar-based verification or any other secure verification method you offer, so that I can regain full access to my account.
