They are scammers. They lure customers to order. My first order arrived timely. I ordered second time in November and delivery date was supposed to be 9 December. It's 18 January and still nothing received. Orders worth more than A$130. I am very disappointed as they I wanted to give as Christmas presents but nothing arrives!
DO NOT ORDER FROM SHEIN. Unreliable and no communication to inform customers what happened to the delivery!
