GFS Express an absolute ****!

GFS Express has been tasked by Temu to deliver my order in Durban, South Africa. It has been out for delivery for days but no joy. They have absolutely no contact numbers, whatsapp or website links that are in any way operational to enable me to talk to a GFS employee. How are they even operating with the overwhelming negative feedback and "****" status online? Why would Temu use them as a courier service if their parcels are not making it to their customers? Why is GFS permitted to continue operating? By far the worst courier service out there!
