SA Post Office shocking

Once again SA Post Office lives up to its poor reputation. I have an international parcel stuck somewhere at arrival. My parcel ordered from China on 08 August 2019 arrived in SA on 21 August 2019. It has since not been processed and/or forwarded. I have emailed customer.services (at) postoffice.co.za to no avail. In response to my email I received a request for a tracking number which I had supp**** (Wow - an actual response). I politely resent the tracking number and now utter silence. I have sent follow up emails asking for feedback and have got the same utter silence response. I expected this response, but hoped upon hope that this inefficient SOE would actually have woken up, but alas, I must have been dreaming and upon awaking I realised that we live in this nightmare. When will this and other useless SOE's eventually realise that if they service their customers they will gain more customers and then their business will grow? When that happens then the profit line grows and amazingly they don't have to rely on bail outs and they can then determine their own destiny. (Scary concept this)
