• Salary & pf dues

Dear Sir,
I worked with a famous institute " IIPM" Delhi. His owner is a popular businessman Mr. Arindam Chaudhary & Dr. Malayendra Chaudhary. I worked here around 1 year but due to reason of salary was so delay i left the organization after complete my notice period. When i left the organization i had my 4 months due salary. After waiting few months they give me four post dated cheques of my dues salaries. But my first cheque had bounce. I communicate with Account department they told me that the will transfer my all salary month by month. But they transfers only my 2 salary in last 6 months. But i did not get any salary cheque last 5 months. They are not giving any positive response. And sir my Provident Fund is also due. So sir kindly suggest me how can i get my dues.

Thanks
Mool Chand
