Employee's Providents Fund Organisation [EPFO] — pf not paid to employees

Address:

Jammu, Jammu and Kashmir, 180004

I am working in a pvt. Ltd. Company which does not deduct pf from the salary. This is approx 18 employee company and has a pvt. Ltd. Label.
They have not given any break up of salary. They did not mention the
1. Basic salary,
2. Hra
3. Any allowances (I am not sure what other things should be included in a salary break up sheet).
They just give a standard amount as in salary without "salary slip".
Please advice me on-
1.in what condition a company does not deduct pf from salary?
2. Why was it not important to give a salary break up?
3. Under what condition a company can be a pvt. Ltd. Company, yet it does not have to deduct pf?
