Hi Asep Sofyan,
I understand why you’d want to buy through an official Microsoft channel, especially if the Surface Laptop you want is not available in Indonesia yet.
If you want to check buying options from Singapore, the best place to start is the official Microsoft Singapore Surface Store here: Microsoft Surface Store Singapore. This page shows the Surface models available in Singapore and lists Microsoft Store Sales and Support at 800-101-3659.
You can try the official Microsoft Singapore Contact Us page here: Microsoft Support Contact Us. After you sign in and choose the Surface product, extra support options such as live chat with a Microsoft specialist may be available.
I hope you’re able to reach the right team and find an official purchase option that works for you.
