This week the guy I book my cruises with (works for carnival) gave me the fax # to use as he isn't allowed to grant them anymore. I faxed over the proof and like 48 hours later I got a email saying it was approved. I was worried at first, but It was a very easy process. I even get another email with the booking showing the OBC on it. I was told it needs to be 30 days within the booking to grant it.
