Parcel stuck at Witspos hub

Parcel number TC ********** 30ZA was sent out on the 12 Feb 2018 and landed at Witspos hub (Branch: JHBNET Comment:C ********** 31) on the 13 Feb and got stuck till today, which makes it almost a week now and the destination is Sandton. I've tried calling the call centers and have emailed them as per the instructions on the website but still no reassurance about my parcel. I'm very disappointed right now! Can someone please get in touch with me
