Skynet poor service

I received an email from Dalene Sithole from OR Tambo on 05/07/2018 stating that my package from the UK has arrived and my ID number was required. I promptly responded with the info. Then I followed the online tracking daily to notice that I had to pay import duties but was never contacted to do so. I kept calling Dalene and was sent an invoice which I paid and sent the proof of payment within minutes to her (note that this payment was from Nedbank to Nedbank). I noticed this morning that there was still no change to the online tracking and called in again only to be told that I hadn't sent through the proof of payment!!! Very frustrated as I am chasing the courier constantly. I am employed in an export capacity and know that it doesn't take this long. Poor service to say the least. Really disappointed as the package is a birthday present. I asked about the possible time frame for delivery and was told that I will receive an email later on...never happened....
