• Employee Provident Fund Amount Missing!!

I was working for a company in Pune for 31 months between Jan '04 and July '06 and had a EPF deduction on my remuneration. After I quit, I applied for the withdrawal of my EPF amount (approx 22,000). First, I did not hear from the EPF Dept or my ex-employer for a long time, because they misplaced my forms and documents. I had to resubmit everything again. In the interim, I lost a little track of the status and after a gap of about 2 years, I went back to check status. At the EPF office, I learnt that my EPF amount had already been paid off and the officer there told me that the pay out was done in July '08, which took me by surprise, since I had not received any such credit to the bank account that I had mentioned on my EPF withdrawal documents.
I spoke about this with a friend who said that my money seems to have been fraudulently missing and that I take some action to get back what is rightfully mine.

What I want to know is, What now, should be my course of action??
