If your first-time employment is after September 1, 2014, and your PF salary is more than 15,000, you cannot become a member of EPS. Your employer wrongly diverted the amount to the Pension fund. Approach the previous employer to give a letter to the concerned EPFO and rectify the mistake by issuing revised documents (they might ask for Form 3A). In the meantime, you may also register a complaint under the EPFIGMS portal regarding your grievance.
