I have a complaint to MARHAB SECURITY company....

If your inquiry is related to the company refraining from granting you weekly leave, the following information is given to you:
The UAE labor law has stressed the necessity of giving the worker at least one day a weekly rest and if the employer requests the worker to work on the weekly rest day, then he must be paid an additional fee, and despite that, the employer is not allowed to employ the worker on two consecutive rest days and if the employer disagrees, you can file a complaint against the employer with the Ministry of Human Resources and Emiratisation.
It remains to point to ,,
"Jawabkom" site is a consulting site for various topics and sections, and the site has no relationship with any government agency or interest in any country.
Here is the text of the UAE Labor Law, related to your inquiry:
Friday is the normal weekly day of rest for all workers except for day laborers. If conditions warrant that the worker be employed on this day, he must be compensated for another day of rest, or he must be paid the basic wage for normal working hours plus an increase of at least 50% of that wage.
