What happen?

The emails I sent to you bounce back, saying your email address not valid. Don't tell me your company block emails from outside? I sms ask you, and you never reply, I think you never receive...what happen??? I can't reach you..................... :(

Btw, this is from Yes 933:
喜欢创作歌曲的朋友可以把作品mp3电邮至yes933@mediacorp.com.sg,说不定有机会被佩芬选中在新节目[创作初体验]中亮相！[创作初体验]3月12日开始每逢星期三下午4点20分播出！

Maybe you can sent your songs too? But must be in MP3 format.
