Limitation period for labour related matters

Dear Sir,

I have worked March 2008 to July 2011 in Mushrif National Construction LLC Central Market Project Souk - Abu Dhabi. My job designation was IT Assitant, my salary was Dhs 3200/- per month. Also, they have provided yearly two-way tickets and leave salary benefits.

In July 2011 I went to India for long leave. The company terminated me on January 31, 2012. After that, they calculated my indemnity money Dhs 6044/-. Partly they have sent my pending salaries and my indemnity money, they have sent only Dhs 2000/- till now. They did not pay my balance indemnity money Dhs 4044/-.

I have sent a lot of emails and mobile calls with no response from Mushrif National Construction LLC. Kindly please help.
