Package stuck at JHB INT MAIL CENTRE for months

Can somebody explain to me why my package (and many others) are STILL stuck at the JHB Hub?<br> Tracking number for one of these are: RI***ZA. May I fly down to JHB and fetch it from a pile? <br> And PLEASE don't ask me to email my tracking number to some random post office email address or 'customer services', that usually leads to them sending me information I already have.
