Employee's Providents Fund Organisation [EPFO] — name change not approved even after 2 months

Address:

341, Bhavishya Nidhi Bhawan, Bandra (East), MUMBAI-I (BANDRA)-400 051, Mumbai City, Maharashtra, 400 051

I have applied for name change in august 2019 as per aadhar and the change is approved by my employer. But it's still pending in bandra ii office for over two months.
I registered grievance in epfigms.gov.in portal three times and it was closed without any resolution all the three times. I don't know how to proceed further since there is no replies to mail or calls also.
