Poor parcel delivery service

i have been waiting for a parcel since Tuesday. Right now its 14:17 on 22/05/2015 at a post office and they don't even know. I have been trying to call customer services and their speed services, i have never been on hold this long. A teller at the branch is calling speed services as well and on hold for 10mins. The parcel is confirmed to be in cape town. How the hell did it get there with an address written for roodeport jhb. The speed services agent drops a call when the teller was asking why the parcel is there. What kind of service is this???? Somebody help me understand this coz right now I AM AGITATED!!!
