Hi wadhera ... You have a right to claim your monies for the job you are doing. There are two ways you can approach the company for payment of your dues:
(1) You have a word with your line manager/employer regarding the concern and give an email to your line manager regarding your query and the discussion you had. If your line manager/employer is still not paying you give weekly reminders to the email. Be polite in your emails and express your need for reimbursement of past dues.
(2) If the option provided above is not working then you may give a legal notice to the company for payment of your past dues. Remember such an action may go against you and hence always consider the second option when you feel that you have job in hand and you are ready to claim back your dues. Before you exercise option (2) remember to store with you hardcopies of all documents and emails that you have written to your line manager/employer.
