SHEIN ORDER

My SHEIN order has been on "out for delivery"since Monday and they called me on Monday to confirm my address and my package was on the road but since Monday till today its Thursday my order have not arrived and when I write to them they tell me about 42hsr to 72hrs that I still have to wait for after tolerating no contact from them I'm the one who's been calling and they always tell me to wait I have no patience left in me.
