You can definitely report the matter to Human Rights Committee and they will step in to stop this inhuman treatment. But the sad part is that your company may retaliate by cancelling your visa and sending you home. Such an action is taken by companies of this type to send a message to other employees of the company and this allows them a free hand to continue to do whatever they want to.
In your situation, however, I suggest you do report the matter to Human Rights Committee as you are suffering mentally, financially and health-wise. I guess there is a limit to endurance.
