Claiming dues upon termination without notification

Good evening,

I am writing to you in hopes of any help you can provide me.

I have worked for a company in Dubai. Last week Aug 3, 2021, I was terminated (well I am not sure if I was terminated, because my visa expired on May 10, 2021, and the employer did not renew it). They asked me not to come to work anymore.

On top of that, the employer did not pay June and July salaries (technically I worked with them till Aug 3, 2021). Now, my employer is refusing to pay me any of my end-of-service benefits.

I have not received any end-of-service benefits and they are not being cooperative. I am begging for any help you can extend. Even legal advice on my situation will be dearly appreciated.

I am appealing to anyone in your office to please help. Moreover, they have my passport with them, and I am staying on fines in the country since my visa has already expired on May 10, 2021.

Thank you for taking the time to read this!
