As a fellow Australian, I can understand your frustrations. It wasn't until I started reading threads on Reddit that I realised AU Sephora Online is actually based in Singapore, not here (which explains the lousy returns policy compared to overseas!).
I had a similar negative experience after spending over $300 during a Points Multiplier event and not receiving additional points. It took several emails back-and-forth to the tune of 'that is misleading and against Australian Law' before they eventually credited the points. It was frustrating and they initially told me that it was because my account didn't exist when the promo begin (which is irrelevant and not mentioned in any T&Cs), but could be what they're trying to get at in your situation.
The best thing you can do is take your money elsewhere. With Mecca and Adore Beauty here, there's really no need to go to busy and messy Sephora stores, and I agree with the other posters that it's probably not worth the stress. The 'black membership' gift took me ages to finally add to an order (acting entirely on principle) and it was garbage anyway. I have vowed to never order again due to bad service, so will also miss my birthday gift if that helps.
