No reply from JHB INT MAIL CENTRE (HUB)

I have a package (RI***ZA) that cleared customs on 11 June 2015, according to correspondence from customer services on 12 June which further indicated that the item would be dispatched within a week. The parcel has not been updated on domestic track and trace and an email sent to JIMC customer services on 17 June has not been answered. Please advise on the status of this package
