Regional Provident Fund — 30 percent of PF money came to me after 3 years of wait

This is Bhavesh Mehta PF account # MH/91925/62 and I was working for Connect Energy services India Private Limited in the period of July 2004 to Feb 2006. I have struggled hard to get my PF money from kandivali office since last 3 years. Finally, the PF money came to me which is only 8941 Rs. All my colleagues (PF account # MH/91925/61 or 63) have got their full payments which are close to 25000.
A sum of roughly 15000 including the interest rates till date has been siphoned off from my account by some CORRUPT PF officers. Right now my company stands closed but does it give them the right to EAT INTO MY MONEY.
