Parcel at Witspos since 17th January 2015

My parcel was posted from Caledon to Johannesbirg on 15th January 2015 and has been sitting at Witspos sine 17th January 2015. I have telephoned the Customer Services centre and emailed them without any change happening, Today I spoke to Simon at the Customer Services centre who advised me to call Witspos direct. I tried but the 'phone just rings and finally cuts off.
