1. Send emails to request for your salary, print out everything and keep it yourself.

2. Backup your work logs or emails. You need proof to substantiate your claim that you were employed. Gather all the contracts, print if you need to as it's really important.

3. If they don't reply your email regarding salary, send them a stern warning that you will be requesting for legal help. Again print out everything. The reason is because there is a chance they may reduce compensation to you by rebuting that you are not giving enough warnings, so make sure you do.

4. Seek legal. Don't care about the cost. (it won't be paid by you anyway) Most importantly you must have all the documents needed to claim.

5. Chances are they will start paying you once they see the lawyer letter. Better to settle outside court than within.

Not that ministries don't help you but there's a proper channel. This is not the time for you to criticise government. You earn a good salary and you can hire a lawyer yourself (and the cost will be beared by your company since they are at fault grounds)

You may wish to seek legal help now. Consultation don't cost much and they will give you much better advise than forumers here.

Good luck.
