The local branch is letting down this international brand

I ordered a parcel from Germany and had it shipped via UPS, and paid a small fortune for the shipping. It amazingly arrived in South Africa in less in than 2 days, which was amazing. The parcel then took 3 days to clear customs, and was sent out for delivery the next day. As per usual I was contacted by the operations for an access code for the driver which I promptly provided, but when a few hours had gone by and the driver had not used the provided access code I re-contacted the operations department and a new gentleman answered and said he was just starting his shift and would follow up for me. He then contacted me back saying that he was unable to contact the driver, but he would keep trying. I was not contacted again, but saw that my parcel was taken back to the delivery hub with the reason "The receiver was not available for delivery. We'll make a second attempt the next business day.", which is nonsense as I know the driver did not use the access code provided as per our access control system. I then contacted UPS South Africa early the following business day to give them a new access code to ensure that the driver had what he needed to make the delivery, and was told that the operations department will be informed of the new access code for the day but if I hadn't heard anything by 12pm I should call back. I then called back at 12pm after hearing nothing, and noticing that the access code provided had not yet been used, only to be told that the delivery would not be taking place today as it was being handed over to Courier IT for delivery the following day. When I asked if this could be expedited or escalated I was told no as the driver had already left for the day. It is absolutely mind blowing to me that, after paying a small fortune for shipping, my parcel could arrive from Germany in South Africa in less than two days, but has been in the country for 9 days and I still don't have my parcel. The local branch of UPS is really doing a disservice to this international brand.
