Adsense approval seems taking long

I already surpass the required page views and unique visitors, already has 89,758 on my visitor stats on dashboard. But seems it takes long till this adsense approval be approved. Im stuck at this thing "Wait for the final approval of your account. Until the final approval empty advertisements will be shown. Do not remove them from your website!" My friends made their approval 3 days after they send their approval. But mine seems taking long. Also their is no email sent that i was been rejected nor approved. Can anyone enlighten me whats happening on this why it takes long?

Please altervista staff reply on this matter, I need voice on this problem.
Also their is no empty advertisement, thats why google doesn't see my blog to be approved?
