Someone please close this pathetic company down!!!!

I ordered a parcel from China a week ago, funny enough, TNT is who China actually uses to courier/ship their stuff to South-Africa. I used the TNT Track & Trace app on my phone and all went absolutely well, until I paid them the VAT etc. The App and even the Track and Trace on their website showed that the parcel will be delivered today(2017/10/06) before 18:00. Yesterday the App and website tracking showed everything is fine and delivery will be done before 18:00, Man, I thought TNT maybe upped their game a bit, BUT, i went onto my App today, DELIVERY was set for TODAY, and the App showed me that my Parcel is in PORT ELIZABETH!!!!!!!!!!!!!!!!!!!!!!!!!!!! OMFG, I stay in Johannesburg, 5 mins away from OR Tambo, where they first indicated my Parcel is and will be delivered to me today but my F-ing parcel is in PE!!!!!!!!!!!! How is this even possible? How much complaints must be given before someone actually steps in to fix the issues in the company? I have tried calling customer service, I contacted the clearance department and NO ONE answers, I contacted Head office and the receptionist keeps putting me through to phones that are not getting answered!!!!!!!!!!!!!!!!!!!!!!!!!!! I have paid good money for the product and almost Seven Hundred Rand to TNT to get this parcel and NOW? Now my parcel is somewhere else and previous customers to them also complained and weeks, even months later, still not received their parcels!!!!!!!!!!!!!!!!!!!! I personally think that TNT is a **** company that is *****ing peoples money.
