Bad Customer Service

I have just had such a bad experience with Buffalo International. I have always ordered staff online, and Buffalo will deliver. I recently ordered from a different supplier and put my very same address, which they already have on their system. The parcel never arrived, and I kept on getting messages saying my delivery failed due to a poor address. I call them to ask what is the meaning of a poor address. The first lady I spoke to from the Kempton Park office was rude and told me they couldn't do anything from their side and that I must speak to the supplier to update the address. I kept telling her there was nothing wrong with the address; it was the same address I had always used. When I contacted the supplier online, they told me they could adjust the address after the parcel had been dispatched; I must speak to their delivery partner, which is Buffalo. I then called Buffalo again and spoke to someone in the Cape Town office who was willing to assist. She said she could see that it was the same address as the other parcels that had been delivered. She would update the system, and my parcel would be delivered. Then, the following week, I got a message again saying the delivery failed due to a poor address and I must pay the delivery fee again. I then called the Kempton Park office again and spoke to Zandi, who refused to listen to me and see why this could be my fault, that their driver could not get the address and could not call me to confirm the address. She say the driver is getting the street name which is just outside the estate, why didn't I write the street name that the driver is picking up. As much as I tried to explain that, it's because I do not live on that street; if I had written the street name like that, it would not have been a true reflection of my address. The driver needed to get to the security access, and my street was inside the estate. He needed to call me for an access code, so I would have given him access to the address. She was not having it. The manager did not even have the decency to come to the phone and try to resolve the issue. She/He just sent Zandi to tell me I must pay another delivery fee. When I asked what difference it would make, my address had not changed cause I had not moved from my address. I was told if I didn't pay another delivery fee, my parcel would be returned to the supplier. The client service from both Zandi and her Manager was pathetic. They did not even look at the fact that their driver might be wrong for not calling a client before driving back because if he was really on the street outside the estate, he was there; he could even see the name and the entrance of the estate, he just needed to call.
