Australia / Prospective Marriage Visa - Australia [2]

Hi. I'm an Australian. Engaged to a Polish woman. We are young - mid 20s. Was wondering if anybody out there could write about their experiences. We've applied for a prospective marriage visa and were told that my wife to be should expect an interview within three months. Those three months came and went. So now wondering what to do. E-mail the embassy? Call them? Really not sure what to do... :O(
