Courier not delivered

We couriered an important document parcel with Speed Services (through the Post Office in Simonstown) to Mozambique on August 25. When sending the parcel we were told it would reach its destination in 3-4 working days. 7 working days later the parcel was still not received in Mozambique. We tried to track it online which didn't work. We went to the Post Office in Longbeach Mall to track it on our behalf. They supp**** us with a phone number of Speed Services in Cape Town where we should enquire. The number provided didn't work. The Post Office Manager took 2 hours to get hold of someone at Speed Services to enquire reg. the parcel. An email containing the details of the parcel was sent by the manager to Dawn Peterson who promised to forward it to their Intl. Division. Despite following up 3x this was never done. We followed up with the Post Office in Simonstown, which promised to get Speed Services to call us and provide details on the whereabouts of the parcel. Noone called. 14 days later the parcel was still not received. We redid all the documents and resent it with DHL. The Post Office is unsure if we will even be refunded for the courier fees paid. So much money &amp
