Poor Service from iMile Logistics

I do not appreciate the lack of communication with this courier service from Shein. I ordered on the 30th of October and till today I still haven’t received my order. The other day the order said delayed by 3-5 days and now it changed to 5-7 days. I have tried to contact them multiple times and have received no answer. I tried to WhatsApp them as well but they’ve been saying an agent will be in contact with me. I changed my delivery address to my address in Pretoria as they were saying they do not cover the area of the address I had initially put in but the order is now in Polokwane. I am fed up right now because I have been trying to get in touch to correct any mistakes and enquire about where my order is. Please do something about this because I can’t keep waiting anymore when my order was supposed to be delivered a long time ago. The delay and lack of communication is honestly nerve wracking.
