To know how can i get my all money from this fraud university

Respected sir I worked as an Assistant Professor in the Civil Department of the School of Engineering of ITM University from 15 July 2015 to 13 February 2017 (total 19 months), of which 1000 per month was counted as Security He did this for 12 months. That is, thus my deposit amount is deposited with the institution of 12000 rupees. After leaving the work, you should go back. Which is not being done on my request. Similarly, the work done in the notice period (January to February) and the wages of the month of December have not been given till date. And the experience certificate of the work done by the applicant was given 5 months after leaving the work. As a result, the applicant faced a lot of difficulty in applying for another job for another five months, causing a significant trauma to the petitioner and there was trouble in feeding the applicant. WHAT SHOULD I DO. I ALSO SEND NOTICE TO HIM BUT THEY DID NOT REPLY. I WANT FILED AGAINST THEM WITHOUT LAWYER. I WANT FIGHT AGAINST HIM. SO THAT THEY WILL NOT DO SUCH THING AGAIN.
