Illegal transfer of my father’s shares to my uncle’s name

2 years ago

Greetings of the day !
My father was holding 100 shares of Alkyl Amines Chemical Limited since original IPO allotment in physical forms. Then after my father passed away on 16/02/1998. Recently one consultant came to our old residential address, where my one of my uncle is living and informed that he can de materialized the said shares in his account. After deciding consultation charges they started process with doing signature of my father(as my father passed away on 16/02/1998). But 10/03/2021 the said application is rejected due to signature miss match of my father. Then after my uncle & consultant again proceed the same with some more perfection and filed revise application for share transfer & for de-materialize the said shares. But on 25/04/2021 my uncle expired due to COVID. I guess in this matter other my family member like other real uncles are also involved and they contact the consultant and forced him to keep continue the same process.

I am knowing all the said facts as after my uncle passed away i kept his mobile phone with me and all conversation is recorded in his mobile phone.

Now I am asking that can i treat this case of fraud?
And what should i do to get my father's shares back- Approx value of shares is Rs. 7.2 Lacs?

Any one pl advise me for faster addressal.
