Customs clearance process inefficient!

I contacted DHL about my inbound parcel ( ********** 885) yesterday to start the the clearance process. I spoke to Kedibone who took my details and promised that an invoice will be sent. A day later NO INVOICE. I call again and speak to Jaco who also promises that the invoice will be in my inbox within 30 mins, and that he will contact me if there's any issues. 3 hours later...NO INVOICE! I call again and this time speak to an Azola, who after having me on the phone for 20 mins manages to send me the invoice. I immediately try to use the online payment portal which doesn't work. I do an immediate EFT and send proof of payment to the ********** address. Another 3 hours later, the status online tracking still reflects "waiting payment". I call AGAIN (note that every call you have to wait an average of 7.5 mins to get to an agent to help you). This time I speak to patience who says my proof of payment is not in their inbox so I must please forward to her. I've just done that, meaning this will only now be submitted to SARS for clearance...meaning my VERY URGENT parcel will stay with DHL for the whole weekend because of inefficiencies that were easily avoidable. For the amount of money one pays this is nothing short of appalling.
