Shocking service from UPS

UPS South Africa has some serious work to do in terms of customer service and last mile delivery. I ordered a product from Ireland on the 25th October 2025. It was tracked leaving Ireland, via Germany, and into the Johannesburg warehouse. There is sat for a month - until 28 November. When I called they said that they had no contact details for me (?) so couldn't deliver. I gave them email, phone, and address details again and they assured me delivery would be within 2 -3 days. I called again on the 10th Dec, and went through the same process, only this time I was told that the parcel had been rejected. As I'm the only person home to receive it, I was puzzled at this. Again, I was assued that delivery would take place in 2 - 3 days. I called again on the 18th Dec and was told that your drivers couldn't contact me... which is odd since she gave me the correct contact details when I asked her to confirm. She then said that they had handed the parcel to DSV who would be delivering on the 19th. Today is the 20th - a Saturday so UPS customer service is closed - and no word from DSV, no contact from UPS, and no parcel. Now what?
