DHL Poor Service

I am appalled at the poor service I am receiving from one of the most reputable courier companies around. DHL i put so much faith in you to deliver a service as you were highly recommended for you efficiency and speedy service but all you have done is let me down. I have sent a parcel from Cape Town to Maputo Mozambique and did my research with your consultant to verify if the contents of the parcel may be sent. I was informed that it is all good and well, only now for the parcel to arrive at DHL in Mozambique and there are clearance issues which now has me on the run around. Why was i not made aware of these terms and conditions when booking the collection? Explained to what would be required? In turn, documents have been sent to me in Cape Town from Mozambique - These documents are of an urgent matter and was booked for collection on Wednesday 21 April 2021. They were collected by your driver in Maputo but the documents were left un attended until yesterday afternoon at 16:45. Only then had someone bothered process the documents for shipment. For 24 hours the package was not tended to and it was requested upon booking the collection that it is an URGENT delivery and that it needs to be sent with OVER NIGHT SERVICE. This did not happen as only yesterday Thursday 22 April 2021 the documents were processed for shipment. I phoned DHL this morning to complain about this, and i was advised that a case had been opened for urgent delivery. That has soon as they land in Joburg it will immediately be sent to Cape Town to ensure that it gets delivered TODAY 23 April 2021. After waiting all morning for feedback i then called DHL myself and was informed that the documents had missed the flight to Cape Town and there for the documents will only be delivered on Monday 26 April 2021. This level of service is appalling, I requested an over night service which has now become a 5 day service. The nature of these documents are very urgent and I depended on DHL to deliver a service. It doesnt seem that anyone felt any urgency to get the documents processed for shipment in the first place at the DHL branch in Maputo, and in tern this caused a domino effect leaving me in a very difficult situation to explain why these documents are not at hand when needed. Who is going to take the blame for this? 2 experiences in 1 week with DHL and its been the most unpleasant and stressful experiences yet.
