SA Post Office/Customs: Delivery of Parcel

Good Day

I ordered a parcel from the USA on the 23rd of June 2018 and have been waiting for it ever since. I received my final waybill number two weeks ago and I started to track it on the South African Post Office website but the status has been the same since then i.e. ON ROUTE.

I contacted SA Post Office today via their customer helpline and the operator indicated that the parcel has been at customs since the 2nd of July 2018. I asked the operator if I need to submit additional documentation for it to be released. He/she stated that it is not required and that the parcel will be released shortly. He/she could however not provide me an estimate time of delivery. He/she gave me a Customs contact number but when I got a hold of someone there the person said that I must contact SA Post Office for the issue. It feels like I am going back and forth between the two parties namely SA Post Office and Customs but there is no resolution? How do I solve this?
