If the application is complete, getting an acceptance or a rejection letter is the second step. First, you will receive the file number with which you can track the progress of the application. While applying, did you use a reliable mailing service with a tracking number (to ensure, if they received your application or not)? You can send them a fax stating that you haven't heard from them. I don't know the current processing time, but back then (around four years ago) you would get a file number anytime between 4 to 9 months. All the best.
