IDBI Bank — idbi home loan - lost my original title/deed documents

IDBI Bank has lost my original title deed in Dec 2017 due to fire accident in Mumbai and never reported this to me till today, i.e., 27th Dec 2019.

I have closed my Home loan in Nov 2018, however couldn't follow up with the bank to collect my documents as I was abroad.

Now, when I am trying to collect the same, I have been handed a letter that's just typed infront of me saying my Original Title/Deed documents were lost due to fire accident and they have given me certified copies.

Searching on the net and on this website, I have come across someone got a letter from the IDBI Bank that states the below
"In order to avoid any inconvenience that may be caused to you in respect of your property, IDBI Bank, at its cost & expenses will initiate process for recreation of title deeds and loan documents."

I wonder, what I need to do in order to push IDBI Bank to do the same for me, i.e., recreation of the title deeds and loan documents for myself.

Thank you in advance for IDBI Bank to looking into this matter!

Best regards
