HCL Technologies — uan update:date of joining

Address:

Bangalore, Karnataka, 560084

Hi,

I was working with hcl technologies from 4 jan 2007 till 24 jul-2015. My employee number was 40169140.
Date of joining is empty in uan portal, because of which i am unable to withdraw pf.
Despite of multiple mails to [protected]@hcl.com to update the same, no one is responding. Can you please help in getting this updated?

Regards,
Nasir n g
