Bad service at Postnet Gordon's Bay

I sent my parcel on the 18th August 2020 with postnet Gordon's Bay in Cape Town, my parcel was accepted by Mike. On the 24th I went back to them to ask what is with the delay as it hasn't been delivered, he called their call center and they said they gave it to a third party and will get back to me with the details. On the 25th I went back because I hadn't received any form of communication. Mike told me he is still waiting for response from the third party, I asked him to call them and he said they only communicate via email. I feel like Postnet doesn't care about the content, and urgency of the parcel I sent, Mike keeps telling me there is nothing he can do but just wait. I am disappointed
