Shocking service delivery (or lack there of)

Placed an order with SHEIN in February order shipped and delivery attempted on 6 March 2024 however no one was home to receive parcel. Parcel returned and to date 2nd delivery not done. i have called several times to find out what is happening and each time the agent spoken to tells me a different story. Last update on their tracking system was 1 April and still I wait. I am starting to think that my parcel is now missing. Moral of the story make sure you are available to take delivery otherwise you might never see your parcel at all
