Company deducted bond amount and is not making other payments

I am a software developer in Mumbai. Company is a Indian pvt ltd. I have recently resigned from company. I had served mutually agreed notice period. 1, company deducted bond amount of 1 lac from my salary although they have not provided me training & not met mutually agreed terms. Company refused to provide photocopies of bond & the letter against which they are claiming the amount. 2, the company is not paying the annually paid fixed incentives which is always payable to me if I resign after 12 months. I have resigned months after that. 3, over phone, HR has told me they make people sign these letters according to their lawyers advice & do not follow everything which they write in these letters, but they have to write those things as it is their legal reqirement. HR refused to write this in email to me, but I have proof. 4, the company is forcing me to settle first after which they will give me signed payslips, Form16 and letters for not crediting salary. Kindly advice?
