EPF amount is credited to another's account - how to get back?

I m working with a reputed mnc company. i observed that from last 4.5 years my pf is credited to another's company left employee. It is totally company hr dept fault as while submitting pf they put wrong pf no. I found that another pf no is appearing in my payslip. I brought into notice to hr but they told me that that is also ur another pf no but when i checked with the help of an expert it is not mine. Now pls advice me how can i get this 4.5 years amount with interest back

Firstly these mistakes should have been averted in the beginning itself by HR team.
Since two years UANs are active and the UAN is created upon submission of ID proofs,as such this should have come to light then.
Available option now is that your HR needs to give a written request on the case to EPF department to correct the details in the records and get the amount into your account.

Sir,
Is it right to lodge a complaint against hr. As i am doubtful to regain my pf amount with interest. And if so where should i hv to lodge a complaint . pls advice

You can record your grievance in the company's grievance cell or committee if you have any or else give a report to his boss.

Thanks Sir
I hv one query is it right to lodge a complaint in regional pf commissioner RPFC office. Pls advice

Yes, you can bring this to the notice of RPFC, as ultimately it is only the RPFC which will have to help in rectifying the gross mistake.

Dear Atuwadekar,What were you doing all these years? as an Employee is it not your Duty to download EPF PassBook & inform about discrepancies to your Employer in writing?
PF Office has nothing to do with your particular case.Without wasting time, take up the matter with your Employer in writing with documentary evidence, can you upload your latest Pass Sheet?
