Poorest Service

I have a complaint about poor service and refusal with my refund. I booked a parcel to be delivered at Pretoria with Post Link Mall@55, my parcel was collected by Courier Guy from Postlink. Courier Guy did not deliver my parcel to the Magistrate Office and the parcel was returned to the Postlink. Postlink is refusing to refund me my money as I must still deliver this parcel that both Postlink and Courier Guy failed to deliver.
