Still no delivery and no communication or responses

I have placed an order from China to SA, and they use Sharp Logistics. The parcel has arrived at the SA hub on 2 Dec 2022. Since then no updates. I tried calling the number displayed on Google for Sharp Logistics, however there is never ever any answer. I also tried emailing - no response. Then I tried the Google chat option, where somone responded after a day. They informed me a driver attempted delivery on 2 Dec but tried to call me with no answer. I asked when will they deliver again and the person said they'll ask if the driver can attempt again 'tomorrow' (that should have been today). No delivery. I tried calling again - no answer. And I tried communication through the chat - no response. This is some of the worst courier companies I've ever had to deal with, as there's no communication whatsoever. This parcel is meant for a Christmas gift, now I don't even know if I'll get it on time. Please assist in fixing this. I don't understand how this is so difficult to get right.
