Shein — not received my order

I have ordered 7 items from shein and the order number is hak67838 on 6th july 2019. I have already paid for the order through net banking and the app is showing only the shipped status regarding the order from 11th july 2019 and is not giving any further information. I have been waiting for over 17days now for my order which is quite a long period and i want my order to be delivered as soon as possible please.
