I did this claim before and it's pretty hard if you don't have a friend or siblings in Singapore. You can't make the call here as you need someone in singapore to make the call for you. You must first send a complain through xbox.com/singapore and wait for a service number. You then need your friends/ siblings to help you call and register under their address. After all this stuff is done. Just wait for them to notify you when you can go and pick up your refurbish xbox360. Its a one to one exchange so you don't have to wait. ( I am not sure if there is a new way, I just did it last year. )

* Easier way *

Send to gamershideout and they will handle all the procedure for you **

Chill bro, actually you were just caught in a bad time cause they just went for the Singapore service 2 weeks ago. So have to wait till end of the month before they send again.

I feel your pain qeeves but trust me. Its worth it. I rather pay then sit 5 hours of bus. It was intense !
