HCL Technologies — Date of Exit not marked for PF account for company acquired by HCL

EMPID 51589408
Name: JAIN SANMATI SURESH

I became HCL Technologies through acquistion of Concept2Silicon Systems Pvt Ltd. My PF for the acquired company Concept2Silicon Systems PVt. Ltd. was maintained in EPFO account: PYBOM[protected].
I am not able to initiate PF transfer from the above mentioned account to my current employer account as date of exit is not marked. I requested HCL PF department multiple times to update my date of exit in PF portal but the response is evasive and no action taken even after follow-up.
HCL PF contact is insisting for resignation letter from Concept2Silion systems pvt ltd, however it is not possible to produce as I just transferred from Concept2Silion Systems to HCL Technologies through acquistion, not resigned.
