You'll get a reply next week. Adsense support is notoriously slow. Behind the scene, your emails are going through multi-bureaucratic-level of personnels and finally to the decision makers to forward the reply to you. What they're doing now may be selective testing. They pick some publishers randomly to do some research on WU option. They may use the collected data to decide whether to support WU in your country or not.
Here is the answer: Western Union Quick Cash is only available in Argentina, Chile, China (Mainland), Colombia, Malaysia, Pakistan, Peru, the Philippines, and Romania. We'll be sure to let you know if we're able to offer new payment options to additional publishers. And here is the source where you will find everything related to WU payments. http://adsense.blogspot.com/2007/10/new-western-union-payment-method.html
No problem with WU to use in Malaysia. Quick and easy just 5 minutes to receive money from google. lol
