Randstad India — employer is not correcting my father's name

I'm sowjanya, an ex employee of randstad, hyderabad. Long back i have submitted aadhar proof and joint declaration to my employer for the correction of my father's name. The concerned team of pf are not responding to my mails. It's been 3 years since i have left the company and currently for more than 2 years im not working anywhere. Till now no response even after multiple reminders regarding the correction of my father's name. Is this how we are to be treated???
