My parcel has been stick at the JIMC for 2 weeks!

My parcel RI***ZA has been stuck at the JIMC for 2 weeks. Every time i try to call i get no response. I eventually decided to go there yesterday but they were unable to retrieve it as it was already in a trolley and i was advised to wait until delivery. It was a complete waste of my time. Why am i trying if the Post Office wont try on their side. This is unacceptable. I need this parcel asap.<br> <br> I also have another parcel LK***US said to have left the US 2 weeks ago, however there has been no update in SA, and no one is able to help me with one either.
