Zero services even if paid to deliver

I would give DHL zero rating if it was possible!!!!! Paid DHL to deliver a international parcel, they collected the parcel on the 27/09/19. According to DHL it would be delivered on the 30/09/19, the waybill nr shows it arrived in JHB on the 30/09/10. On Wednesday 02/10/19 morning it arrives at Pretoria hub. Then suddenly it gets transported back to Johannesburg on Wednesday morning before lunch. The customer care lady tells me oh sorry it needs to be handed over to third party delivery to be delivered to you (aka RAM couriers) so I ask to have it noted that the contents of the parcel is needed urgently and to have it collected by RAM the same day please. This morning 03/10/19 I still haven't heard from DHL or any other delivery company regarding the delivery of my parcel. At 9:30 I contact customer care again onpy to be told that the third party couriers only collected this morning and delivery should take place tomorrow which will be Friday 04/10/19. How is this acceptable? I paid for a service due by DHL and only to be told three days after delivery should have taken place that they will be handing it over to someone els, that takes another two days for delivery if I am lucky? To me this is TOTALLY unacceptable!!!
