Myfotowink,
I agree with Alex and would like to take his comment further by saying the problem in Malaysia is that people seldom challenge employers in a court of law and hence, employers get away with murder. Since you, myfotowink, again described slavery and that the employer confirmed they wish to hold you to non-existent contract terms you didnt agree to, your employer has nothing but hope that you wont pursue them via lawyers because they have no case.
This is off the topic but illustrates the same malaysian mind. An agent showed me a rental house and told me XYZ terms and details. I should say he never actually showed me the house, he only told me about it and I located the owner myself. I took the house and moved in. Following week, agent appears at the door demanding one month's rent as his commission based on "I know you didnt agree to that but thats how we do things here in Penang." I said, NO YOU DONT and I will never pay you a cent. He had bitter words for me, called me a thief and a cheat, threatened to go to the police, call his lawyer, call the neighbors! I said, Great! I'll be right here! I never heard from him again.
This is why, i learned 40 years ago in USA, asians despise contracts. They like to make up rules on the fly, as they go along. Westerners and others depend on contracts for stated obligations for the very reason you and I had the very same problem as to this crazy mindset that will not hold up in court.
To your question, I am not personally aware of immigration's ability to detain or block a person over this and have never heard it said. I have no direct information to share.
You can check with your embassy but I didnt mention it because embassies stay out of local laws. They mainly exist to help you if you lose your passport or something and cant intervene in local disputes. It doesnt hurt to ask, though. Try.
Based on experience, lawyers dont charge for a question and consultation, just when they take a case so dont be afraid to google for one and get on the phone. You can also contact the labor department with your questions but I fear they will be hard to contact and if you write an email, it could be a long time for a reply. Do you have a labor office near you that you can visit?
Im afraid to ask you, when you met with your boss about this and he explained his point of view, did you agree to that or anything? I told you not to! The legal term for this is NOVATION which is the adding on to a contract or replacement of one agreement with another which your boss is attempting and if you agree, you strengthened his position. Had I been in the meeting i would have said, "thank you for your time. I dont agree, I gave my notice and im still leaving on schedule" and walk out.
As to blacklists, here again that is something that could be sued over when the time came, like if you come back. Alex had a good idea, to let you off now and you will return and complete your time later but if you make a proposal like that you have to take care in exactly what you are agreeing to. Likely though, the boss wouldnt expect you back and wants you to pay money now. You need a lawyer to address this firmly including maybe writing a letter on your behalf. Lawyer letters have weight since the recipient will have to start spending money to, in this case, defend a very weak position.
Alex acknowledged what you agreed to originally but like i said, agreements have no force or effect when the premise or foundation of the terms is illegal to start with -- like slavery. And THAT is something you dont want to get into with your boss, thats the task of your lawyer.
