Parcel stuck at Witspos Hub & bad customer service

I have a package (PE***ZA) that is sitting at Witspos and has not moved from there since Friday 10 July. I am waiting for it to reach Bedfordview.<br> I have tried phoning the Witspos centre, and none of the 5 numbers I have found are working. I have also tried phoning the customer service number (10 times a day for 2 days) and the head office number, but no one answers. I have also sent an email to customer service email, but no response. This is insanely bad service and I am very frustrated.
