Capgemini — No response for PF queries

Address:

Talwade Pune

I have sent multiple emails to Allsec and CG Retirals but not getting any response. I have sent more than 15 emails.
Once I got email which was useless as it was with blank form 13 when I specifically asked for details to be filled in the form 13. They dnt even read emails.
These details are needed so that my previous employer help me merge the old account to latest one with CG.

I am not sure why there is no escalation matrix. There is one Mr Sonkusare but he also doesnt reply.
I am really clueless now.
