SA Post Office: out of 5503 Parcels sent, only 2330 Delivered!!!

I sent a parcel containing edibles to Canada early 10th October 2017, it is now 16th January 2018 and the parcel has yet to be delivered. The edibles will now be expired and they cost around R1800.00. I paid R2517.00 to have the parcel delivered and it hasn't even left SA Customs.

I phone and no one seems to be able to help me. Get passed on from one to the other with no resolution. It doesn't help to call Track-my-Parcel as they just refer you back to SA Post Office. I will never use this service again. Now how do I recover over R4000.00. If you look at the website where you rate the service - most parcels never reach their destination, how do they get away with this?

Their current ratings are as follows: Deliveries on Time - 598 Late Deliveries - 1732 Never Delivered - 3173

Who is *****ing the parcels, what are they doing about it and what is happening with the money paid for a service not provided?
