Hi how can I complain a company abbusing to employ...

 you can do as follow:

-file a complaint at the labor office against the employer 

-file a lawsuit before the judge immediately as article 5 of the labor law states as follows:

All the proceedings in the court and filing a case as well as execution of the claim which filed by the worker are exempt from the payment of fees according to the provisions of the law. the court bay accept or refute the case also may decide to remove or impose the fees

It should be noted that after reviewing your inquiry and legal scrutiny we would like to inform you that the work offer is a job offer that is presented to you before the employment contract and you can accept or reject the job offer. The job offer is not considered as a commitment, but the employment contract is the one which is be considered because the contract of employment is the one that preserves the right of the employee and the company to include the terms and conditions, seal of the company, and the consent of the worker to all the provisions of the contract and thus protects the rights of the parties, so we recommend you to go to the Labor Office and file a complaint against the employer and request help from the Labor Office
