Lichfl — Return of Original Documents from NOIDA branch

I had taken a loan from LIC Housing Finance on 24th march 2011 for a period of 15 years from NOIDA branch . I paid all my installments on time or before. I managed to pay back the entire loan in Jan 21. However, I am yet to receive my original deed and documents/Certificates against which I got the loan.

I raised many requests using LICHFL customer portal during this period and received automated acknowledgment. Like below:

Dear AMIT KUMAR MISHRA,

But there is no action after this.
Please Help!
