As of July 2013, there was an internal policy change regarding Google Adsense's Western Union Quck Cash payment to publishers around Asian region. If any fellow Malaysian experiencing WU payment issued currently being hold, please check your gmail for instructions or check out this support forum for more info:http://productforums.google.com/d/msg/adsense/FjEMJH5IRDE/YOKpPICfPf0J
For Malaysia, Western Union have to manually verify your ID first and clarify it with Google Adsense before releasing the WU money transfer. Fortunately, mine was ready to picked up just within few days after following all the steps as instructed by our local WU representative and Google Adsense team.
In the email received from Google Adsense team:
"Moving forward, if the payable balance on your account exceeds $2,700 , we ask you to change your form of payment to secure check delivery."
I'm still wondering is this a mandatory payment option or can I continue using WU but need to manually verified my ID first before releasing payment. Let's just hope we can get more info from Google Adsense soon.
