What can be done if employer is not signing joint declaration form for father's name correction in EPF account

My employer fed wrong fathers name in my EPF account.......I came to know when I tried to withdraw....my claim was rejected.... Now employer is not signing joint declaration form for it

You can also modify your Basic Detail for using UAN EPFO portal (https://unifiedportal-mem.epfindia.g...mberinterface/). You can login to EPFO UAN portal and modify your basic detail by uploading necessary documents online. You can also add your bank detail, PAN, AADHAR, Passport, Election Card & Ration Card Detail.
If you have not yet updated these details on the EPFO portal you must do it now & employer approved your KYC & Basic Detail.
Thanks
