UPS South Africa is really bad!!

I'm sure UPS in the USA is reliable, but in South Africa they are the worst. I ordered something on Amazon USA and it was sent with UPS. Updates on their website was consistent until the package arrived in South Africa - then the updates stopped. I called the call centre twice before I could talk to an agent who sounded perplexed that I didn't just use the website to track the parcel. When I asked her to look into it, she sighed as if she's doing me a favor. Put me on hold for several minutes and then said the package is being sent with a third party due to the remote area where we stay and promised, that it would arrive the next day despite their being a delay. I asked for the details of the third party so I can follow up with tme, but she didn't want to give me the details. The next day came and went and no parcel. I checked UPS website and the update simply showed "delayed" nothing else. Last night I got a message from someone in the neighbourhood who claimed that the parcel was delivered to them - three blocks away from where I stay. She stated the courier insisted that she take the parcel even though she told them she has no clue who we are and that he wasn't even at the right address. Luckily for us, we have a community Whatsapp group and the person was honest enough. I am really disappointed in the poor service. UPS South Africa is really bad.
