Parcel stuck at Witspos and no feedback

I have been waiting for a parcel and its been stuck at Witspos hub. I emailed customer support. Ignored. Not even an automated reply. Contacted the team on Facebook saying i emailed them, got an automated reply there saying i must email them. Sent another email to see if it gets ignored as well. With terrible service like this, its no wonder people barely use the post office anymore. I will never make this mistake again
