Unfair dismissal by my employer due to filing a complaint

I work for my employer starting from 09/02/2021 till 08/02/2023. Earlier, I was receiving AED 2000 total salary. Basic Salary: 1500, Accommodation and Transportation: 500.

Even though my contract states: Basic Salary: 1500, Accommodation Allowance: First Party, Transportation Allowance:  First Party and no amount was stated for such allowances.

My employer suddenly reduced my total salary to 1500 since April 2021 and refused to provide me a decent accommodation.

Upon filing a complaint, my employer arbitrarily dismissed me from work on the 28th of December 2021 without salary from December till now.

He ordered his PRO to throw my laptop bag and belongings outside the shop, locked me outside and stopped me from working till today.

This is my case. Please, what do you suggest I claim now? Because even though my employer terminated me, he never put it in writing but was practically done.
