Mr. Sheik has given valuable advice. Kindly follow it.
Before you visit you may ask even if by email, the company personnel who has replied "come and collect" with a copy to HR -Manager and HR-Head, appointing authority, MD, to supply you the FNF statement prepared by company, hard copy and soft copy, and PF number and attested copy of PF withdrawal/transfer forms (as desired by you) which you shall deposit to PF office yourself, form 16, etc. so as to reach to say within next 7 days, by redg. post and email. If this is not supplied, you may supply a statement (even if by email to the personnel who has replied "come and collect" with a copy to HR -Manager and HR-Head) of payables by company to you, and ask them to verify and confirm that statement is correct, even if by email so as to reach you say in next 3 days.
If there is no reply you may take a witness along with you e.g. cousin, friend, colleague (who shall agree to be and remain your witness), and you may record the transaction (audio/visual). If the company provides a FNF statement on plain paper and asks you to sign acceptance then and there, you may point out the variances if any, or accept the same and keep a copy and demand payment then and there. If the company personnel, state that payment shall be supplied later, you may ask for time period within which payment shall be supplied to you.
During the meeting company personnel may become rude. The recording shall come handy later for use in appropriate forum at appropriate time. You must speak your full name, other person’s full name, address, date etc.
You may also demand other documents to be supplied to you e.g. PF number and attested copy of PF withdrawal/transfer forms, form 16, etc.
Since you have worked for only 4 weeks, probably the company HR wants you to remain satisfied with exp. Certificate, release letter and drop the claim of payment of dues. Or they may handover the back dated cheque to you.
After the meeting you should submit the minutes of discussion by letter followed by email, to good offices of your appointing authority, MD, with a copy to Head-HR and demand your payment by bank DD and documents to be supplied to you say within next 7 days by redg. post only. You may mention that you are enclosing a postage prepaid ( as purchased from PO) self addressed envelope for sending redg. post to you.
Thus you have remained gentle, amiable, and have given sufficient opportunity to the company, and if good offices do not provide relief you may approach your lawyer to issue legal notice and agitate to the O/o Labor Commissioner, Wages Inspector, Chief Inspector as in SE act, applicable to your state.
