Cognizant Technology Solutions — uan data correction and pf withdrawal

Address: Mepz, Tambaram, Tamilnadu, Chennai, Tamil Nadu, 600054

I quit cognizant in 2014 and since then i am trying to withdraw my pf but i am unable to. The reason is my pf account is in the name of another person who is/was part of cognizant. I only came to know this when i tried to withdraw my pf. I am not able to correct the data on uan portal online because, i am not allowed to link my aadhaar since the name in uan is the other person's name and my aadhaar has my name. The only option i am left with is going through my previous employer which is cognizant. I am chasing cognizant on this issue since 2014 but still no resolution. I dont know the cause of the problem is epfo dept or cognizant. Mobile number, email address and bank account details are mine in uan but the name, father's name are someone else's on the uan portal. I have come across many critical situations to utilize the money but due to this issue, i was not able to utilize actually.
