Mr. Vasudevan has given valuable advice. Kindly follow it.
You may prepare a statement of payables by you to company and payables by company to you and ask the company to confirm in writing that it is accurate or point out the anomalies, in writing by redg. post.
Companies do try to convince that it has to evaluate the recoverable from employee and would like to have a hold to adjust in FNF statement/settlement.
However you may show the mirror to company and conclude that company is sitting on huge amounts of your good money. You may raise a very valid question how would you and your family survive without your salary, and from which source company expects you to fund the cost of attending office.
You may mention that you have not been paid your wages on your pay day which is……..as in case of all employees.
No one including a trainee, apprentice can be kept on work without being paid and that too in time.
You need to drill sense into the heads.
