Poor Service delivery

This was the first time I made use of Shein but unfortunately for me... my parcel got lost. Between Shein and Aramax this was only confirmed 6 weeks after placing my order. The problem is trying to get hold of somebody in Shein to assist with what is going on due to the online status of the tracking not being updated. Today I was told by Aramax that my parcel is lost and I must now wait for Shein to decide if they are going to refund me or send another parcel.
