Bad customer service by DHL EXPRESS

I'm so disappointed in the Dhl company for not delivering my parcel on time. I spoke to several agents already and was told different things. My parcel was supposed to arrive this morning after 9am as the last agent i spoke to yesterday afternoon said he has sent an email to have my parcel prioritised for delivery this morning but I went on the web to check on the status of the parcel then boom the parcel was sent to a wrong facility which is midrand and is meant to be sent back to the right destination. I called this morning and spoke to Thabani Moyo who said after the call I made he will call the airport to send to them and the have it delivered immediately. I'm so frustrated right now as I'm running a business which is supposed to boost out S.A economy in this difficult times. I have clients sitting on my neck to have their products. I paid for my shipment as well as the ridiculous tax amount and sent proof of payment the DHl but they I'm taken for ride and not be taken seriously. I want my parcel by 10am this morning!!!!!!
