How To Cancel E-Pass If You Are Not In Malaysia Anymore

I'm not in Malaysia anymore and my employer didn't cancel yet my E-Pass because we have some arguments before my leave, and we hate to see each other. So these are my questions:

1.) Am I required to cancel my E-Pass? What will happen if I don't?
2.) Can I cancel my E-Pass by my self?

Cancellation requires your passport to be handed to immigration for the validity date of the FW Employment Pass to be shortened. This new system is supposed to stop job-hopping and a job to be linked to one employer who has provided the EP. However, whether this is being enforced is unclear. The only risk is whether your employer has reported you as having absconded from the job.

You mean only your current employer can cancel it?
Is this an opinion or a fact?

Because if it is a fact, then what if your current employer is a jerk and they don't want you to jump to another employer, so they just ignore you and never cancel your EP.

It doesn't sound fair. Maybe EP can be cancelled by the employee.

Didnt say only the employer could do it. But you need to be in Malaysia to arrange this as your passport is required.

If I will be the one to cancel it, what is the procedure?

This is the system that manages Foreign Workers and they have some contacts which my be helpful http://www.fwcms.com.my/contact.html
