Correction of my name in epf account with pf deptt chandigarh

I am Uppninder Kaur Thapar. My name is mentioned as Uppninder Kaur in my Certificates/testimonials before marriage. After my marriage my maiden name was changed from Uppninder Kaur Thapar to Ms. Leena Thapar. After my marrage I am being known and addressed by both names i.e. Leena Thapar as well as Ms. Uppninder Kaur Thapar in as much as my name is recorded as Uppninder Kaur Thapar in all my documents i.e. Adhaar Card, Voter Card, DL whereas my maiden name Ms. Leena Thapar w/o Shri Ashavmedh Singh Thapar is mentioned in my employment record of Moti Ram Arya Sr. Sec.Model School, Sec. 27A Chandigarh, which is purely a private school & not aided one. I joined my school in 1993 and my PF was being deducted from 1994. In the year 1995-96 I had requested my school authorities to correct my name as Uppninder Kaur Thapar in service records, whereas it is written as Ms. Leena Thapar, but school authorities did not do the correction. I had submitted an affidavit duly attested by Notary Public. Thereafter again in 2007 I again submitted an affidavit and newspaper cutting regarding correction of my name in school records. It was recorded in affidavit and newspaper public notice that I am being known by both names i.e. Leena Thapar and Uppninder Kaur Thapar, whereas both are the same person and after my marriage I am being addressed and known by both names, but school authorities did not change the correct name in their records. Now my retirement as teacher is due in 02/2018 and my PF Dues are stuck with PF Department due to the fact that adhaar card and PAN card are in the name of Uppninder Kaur Thapar whereas as per PF Number allotted to me by PF Department is in the name of Ms. Leena Thapar, which has not been corrected by my employer. Now PF Deptt will not release my retirement dues and monthly pension before the amendments. I applied to my employer for correction again in 2017, but they simply forwarded my application to PF Office, Sector 17 Chandigarh, but did not sign the joint form submitted by me to my employer. Now PF Deptt., Chandigarh is not making the correction with the objection that for such a long period of time correction of name has been requested by me. In this regard I also submitted copies of Adhaar Card and PAN Card and Affidavit duly notiarised with copies of my income tax returns(in which both names are recorded), but PF Deptt.refused to entertain my application for correction of name in PF records. Now I am in severe problem that my dues and pension would not be released by the PF Department on my retirement. My School Principal is also adament to sign the joint Declaration form obtained from PF Deptt for correction. Please help me how to proceed for correction of my name in PF Account maintained by me in the Office of Regional Provident Fund Commissioner, PF Deptt., Sector 17 Chandigarh. I shall be very thankful to you. Hope to get a reply from your end on my email id [deleted]. Kindly help me.
