Accenture — Regarding Name change in EPFO PORTAL

I need to change my name in EPFO portal and i resigned from accenture on july 17th, i have sent them no of mails regarding where do i need to sent joint declaration form and i did not got any response from them.

I visited the EPFO office Hyderabad today and got to know that i need to submit JOint declaration form and attached aadhar copy to accenture office in Hyderabad and then they will send it to MUmbai (main branch ) for EPFO name change approval.
