Help in a case against a Malaysian company that has been going for years

I have a problem in Malaysia and I need some help please..

I have a case against a Malaysian company that has been going for years and we have paid a lot of money for a law firm over these years trying to retrieve our money back from them without success yet..

The story in short is that we sent a Malaysian company money in exchange to some equipment that they never shipped or manufactured.

We have agreed 3 times through the law firm with them on settlements and every time they only pay one payment out of 12 and then stopped paying.. The last settlement was after a seizure and sell proceeding in which the owner of the company have almost nothing on his name to seize and sell..

Every legal proceeding costs us around 1000 USD and we still didn't get anything from our money yet, and we don't know what to do anymore. And after reaching the law firm last time they are again saying there're two ways to proceed now:

1.   Filing again Writ of Seizure & Sell and do not enter into a settlement if offered; or
   

2.   Garnishee action
   

What can we do to force the owner to pay and stop him from keeping stalling please?
