Shocking "Customer Service" from Fastway Couriers

I have ordered product online, and was so happy to hear on Monday 12 November 2018the order is already shipped! I track my parcel with Fastway today, and it was in the courier's car the whole time and taken back to the depot. At 2pm 14 November, i phone the courier as once again the parcel is in the vehicle but hasn't been delivered. The courier, Ronaldo tells me that he is on his way with my parcel. At 2:44pm I don't have my parcel, so I proceed to phone the depot in JHB. After telling my whole story, I get put through to a person. I don't know who or what, but Sam proceeds to correct me when I gave the wrong name of the receptionist. Up to this point he's professional and i'm very annoyed, but he says he will call me back. He phones back to tell me the courier is on their way (note that as i'm typing this its 3:22pm) and I ask for confirmation of delivery time because i've been told for the last hour it's coming, and explain to him that the parcel was in the vehicle the whole day yesterday. He then says that there's a problem with my address, which just upsets me more because they have my number and if the address was an issue they could have phoned me! He says street name, complex name, area was the address yesterday which is complicated, but today it's complex name, street name and area (exactly the same details) and they will come through. Upset as hell, I then say they've been saying that the whole afternoon, and I don't want my parcel going back to the depot like yesterday. Does he not tell me: Hey did you raise this issue with me yesterday? I'm telling you now i'm resolving the issue. I ask to speak to a manager, they're out of the office. I ask who they are, he repeats they're not in the office. I've been doing business with Fastway since 2008 for my business, well thanks to Sam Mahlangu, customer (NON) service agent, I will stop all business dealings with them and I will also advise every business owner I know to do the same.
