Terrible Service ARAMEX PRETORIA

Tracking ***. Complaint Ref: PRY/0520/243. My package left source on Tues 05 May. Your tracking system says it has reached the PTA sorting hub on 07 May at 1am. The next day it reports that it has reached the PTA sorting hub on 08 May at 1am. The destination of the package is PTA and not in the outskirts - central PTA. I called the PTA office at 12h52 on 08 May to follow up. . My package has not yet been scanned, it has not been loaded onto any delivery van and I would receive it on Monday. I expressed my dissatisfaction with this and was told by Marina that the issue would escalated to management and I would have my package delivered by today. I called in again at 16h33 and was told Marina would get back to me. Why is it taking a whole week for a package to be delivered whereas other courier services can do it faster. Also why is it taking over 2days for a package to move from the PTA hub to a destination IN PTA?
