CETTIRE review please?

Did anyone have any experience to shop from the online luxury goods store CETTIRE in the Netherlands or any other parts of Europe? How long do they take to deliver your order? For me, I placed the order many days ago but till now no update from their end in terms of tracking or anything. I have emailed them multiple times but no response. I feel I got scammed by them, not sure, please help share your views on CETTIRE
