Claiming compensation after termination of employment contract

I'm based here in Dubai.

I got terminated last July 15 and was given a 1-month notice by my employer. When I went to the labour department to inquire if I'm getting any compensation the legal adviser gave me the computation of the amount.

Then I filed a complaint against my employer because they did not pay me the computation I was given by the legal adviser.

Yesterday, I went to the Tawafuq Center to settle my complaint but nobody showed up on behalf of my employer. Instead, the legal adviser called the PRO and they talked.

After they talked the legal adviser told me the I'm not entitled to anything and told me that the computation I was given from Tasheel is wrong. I was terminated because I was absent for 4 days because my grandmother passed away.

The legal adviser told me that I can still open my complain anytime. Can you please give me some legal advice regarding this matter?
