Parcel stuck at WITSPOS (HUB)

I dont know what is happening with our Post Office but their service is just pathetic. I was sent a Parcel from Newcastle on the 28 August 2018 and the sender was told that the parcel will take 3-5 working days to reach me in Glenvista. The item arrived at the WITSPOS (HUB) on the 31 August 2018 at 12:25:00, and was scanned again on the 03 September 2018 at the same WITSPOS (HUB) at 14:45:00. Today is already the 6th working day and my parcel is still stuck at WITSPOS (HUB). Tried calling the call center for assistance but all the agents are busy, I was on hold for more than 30 minutes and eventually had to hang up the phone.

Is there a way that I can go myself to WITSPOS (HUB) and collect my parcel since its hard for them to sent my parcel to Glenvista? Worst part is that WITSPOS (HUB) is just 15 minutes away (9.5km) from Glenvista post office.
