My company has cheated me on my final settlement...

We would like to inform you that If the company does not give you the financial entitlements of termination the employment contract, you may file a complaint at the Ministry of Labor explaining what the company did of not granting you the financial entitlements and any other things that the company has committed against you. The concerned authority will investigate the complaint and compel the company to pay all your financial rights. As there is no provision in the Labor Law obliges you to pay money to your company. Finally, we note that the UAE Labor Law has obliged the worker who breaks the employment contract before its end to pay compensation to the employer not more than a salary of a month and a half.
Here are the texts of the UAE Labor Law relating to your inquiry:
Article (116):
Where a contract is revoked by the worker for reasons other than those stipulated in Article (121), he shall be required to compensate the employer for any damage the latter sustains as a result, provided that the amount of compensation shall not exceed half a month wage for three months or for the remaining period of the contract, whichever is shorter, unless otherwise stipulated in the contract.
Article (121):
A worker may leave work without notice in one of the following cases:
1- If the employer violates his obligations before the worker in the articles stipulated in the contract or the law.
2- If the employer or his legal representative signs an assault on the worker.

The complaint must be submitted to the Ministry of Human Resources and Emiratisation, as it is the authority responsible for examining labor complaints.
With an explanation of all the damage that happened to you.
Until the judge rules in your favor to compensate for those damages

You can register a complaint through the website of the Ministry of Human Resources and Emiratisation

Also, we cannot expect a specific time to resolve the complaint, as this matter is due to the work pressure of the Ministry of Human Resources and Emiratisation.
