International parcels Lost/****** at JHB Customs

I have sent multipile emails to JHB customs Ernest Dlamini & Margret Moremi regarding my parcel being lost at JHB customs. Parcel RI***ZA (Local tracking number) can not be picked up on the system at JHB, but a week prior I received the local tracking number after several phone calls (thus no one answers the phones ***. Up to date NO response from Ernest in regards that my parcel has been at customs since the 15th of JAN 2015, upon calling a week later, the lady from customer services told me the parcel could not be found on the system.... so where is my parcel..... Service is utterly unprofessional
