Please check online about the status of your application at
EPFO. Have you mentioned your mobile number at the top of Form 10C and Form 19 so that you can receive SMS alerts for the remittance of the PF amount into your account?
As mentioned by Mr. Chobey, please obtain the details from your previous employer and directly approach the PF Office with the assistance of the person handling PF-related activities in your previous office.
Never get tense. Always stay calm and composed, no matter what is happening. Act smartly and achieve your target.
All the best.
