NO Delivery or Feedback from EMS south Africa

I have been expecting an item, tracking code LK***US, from the US via EMS postal services since September 2014. I have been on 4 occasions to EMS offices and waited at 4 hours on each occasion. EMS can not tell me where my package is and I need to call the call center to track the package. Problem is no one answers the call centers number. There is no recourse and I cannot get any answer out of EMS regarding my parcel.
