HCL Technologies — pf not transferred completely to my new uan

I left hcl in 2015 and joined dxc (Legacy csc). Raised a pf transfer request and i was told that the pf was transferred. I have joined ey now, and tried transferring pf and got to know pension from hcl was not transferred to csc and hence, my pf cannot be transferred from csc to ey.

Raised the same concern with hcl pf dept. And i have not got any update since 10 days. I have sent the forms but the team is not responding and supporting at all.
Spent a long time in past to get pf transferred and this is an ongoing issue with hcl.

The team are not at all responsible and responsive
