Lost parcel and poor service!

Extremely disappointed with this service. We had a parcel coming from Johannesburg which was shipped out on Tuesday and received in Port Elizabeth on Thursday. We phoned them and they said they'd be delivering the parcel on Thursday. Thursday came and went so we phoned them this morning (Friday). They told us that it would be delivered today as long as it's an essential product and we explained to them that it was. We didn't hear anything all day so we decided to phone at 5pm, everytime we would phone they would pick up the phone and end the call or we would get transferred immediately and the phone would just ring endlessly with no answer. At 5:45pm we finally got hold of someone that said she would phone the delivery team and ask what's happening. She then told me there's no answer she's going to walk to the department herself and see what's happening. When she came back she informed me that the delivery person doesn't have my parcel nor do they, they have no idea where my parcel is. This cost me over R600 and The Courier Guy Port Elizabeth just miraculously misplaced it .
