As I said earlier, send them an email (if you haven't already) that you haven't received the email so that you can show it to them of they ever ask why didn't you send your passport within 30 days (if they have sent it and are assuming that you have received it). I am waiting too, so I understand how it feels.
PS: When CPCO send emails, they schedule it to be delivered on certain date. When they say the email was sent on 27th May (which they tell everyone) we don't know if it was supposed to be delivered on 27th or on a later date.
