Dont know whats going on!

The company I work for are awaiting important documentation and after checking the tracking number on the SAPO Track & Trace I noted that the parcel is ready to be uplifted (1st notification sent on 20/02/2015). We never got this so I sent our driver to the Greyville Post Office in Durban to collect the parcel, however when he got there he was told that I has been sent back to the sender. They gave him the call centre number to call, for which I have been on hold for the last 20 minutes.<br> My complaint is as follow.<br> 1. We never got the notification that the parcel arrived and await collection.<br> 2. Surely there should be two notifications that go out.<br> 3. Why was it sent back to the sender so soon.<br> 4. The call centre SUCKS!!!<br> 5. I`m on hold again for 15 min.
