EPF Contribution Amount Not Reflected In Passbook

Sir,
Some EPF contributions of past months are missing from my EPF passbook. On enquiry with EPF Office, they said it has not been deposited. But I know it has been deposited, because I do the online payment work. How to proceed and to whom to complain. Likewise one of the staff who left the service, his total contribution amounts to Rs. 80,000/-. But he got only 50,000/-. I sent him to the EPF office with CRN number and TRRN number for proof of deposit, But they are refusing to accept this and insist contribution has not been deposited. Please advise.

Hello Friends,
I am also facing the same issue. Last year May month contribution and his year June contribution is not reflected in the passbook and I know that the payment has done.
kindly let me know what I have to do... Please... Employees are asking us as we didn't pay the PF contribution.
