I've walked into the Sydney store three times, each to get a present for someone. Not once have I ever walked out with anything. Their staff are rude, it takes me an age to even catch someone's attention, who then assumes that because I am younger, I cannot afford anything, even when I am in the sterling silver level, and frankly, their products are overpriced. I'd love a key, and I may have a look at Melbourne and see if their service is better, but at this rate, I'm completely out of love with them compared to my initial willingness to purchase. Had I experienced a positive first visit, I'd probably be much more willing to revisit and buy more, but clearly they don't want my business, and that's fine. I ended up getting pieces for my friends that they loved, from other jewellers, who provided me with wonderful shopping experiences.
That being said, I find customer service in Sydney just a bit lacking in general. Slack to say, but truthful. I've found few sales associates who are genuinely helpful and provide the service I expect, and I work in retail part time, so I think I do have a reasonable idea of what should be provided.
