LIC Housing Finance — Return of share certificate

Mahesh Addagatla here.. I have taken the housing loan from the LIC. My Loan Account :[protected] Application No : [protected] . I have submitted the original share certificate to LIC for disbursement of the loan amount. Now i want share certificate back. As required by society.. to transfer the name on certificate. and become the member in society. Since more than a month im following up with Mumbai Dadar branch. Surprisingly no response from any body. No body is picking up the call. On landline number just rings continuously. Mr Dharmesh branch manager also not able give any updates on same. Sending reminder mail on daily basis. but nobody is bother to give reply also. I've been following up with team for over a month now. How is it possible that nobody unable to provide the document that I requested? Don't know what to do? In LIC, there is no escalation matrix, and no one is interested in assisting me. I've only received one email in the January 31st, 2022. Declaring that the request has been accepted. Nobody responded after that.
Please solve the same some one. Please society not allowing me to do anything.
