HCL Technologies — FnF is still pending after 2 months

Address:

Nagpur

I left HCL on 22nd Sept 2019. However my fnf is still pending with them. I am continuously following up with multiple teams like admin FnF, have included HR and Reporting Manager as well. Still no luck. I called HCL helplines but those were not valid.
Kindly suggest if something else can be done from my end or whom should I contact.
