Hello Lnmailid,
Please remember the following with regard to The Employee Provident Fund & Misc. Provisions Act.
You (Every contributory member) will be eligible to withdraw PF accumulation (through form 19) irrespective of the number of month's you have worked (presuming that your organisation/employer has remitted your PF contribution for all those months). However, you would not be withdraw your Pension (through form 19C) since the eligibility requirement for same is a minimum remittance to the PF (& Pension) account for 6 months for any member (by the organization/employer).
In your case, since you have worked for only 3 months, your form 19 would have been accepted by the PF Office whereas the form 19 C would have got rejected (as you are not eligible to withdraw pension amount).
I hope this will give you clarity on your doubts. If not, revert to me.
Cheers, A.B.
