UPS does it again!

Here we go again UPS! Worst shipping company in the world. Package was shipped weeks ago from Hong Kong. Package arrived in SA last week, received the invoice for VAT and Duties last week Thursday, paid it immediately! It is nearly a week later and my package haven't been delivered. Furthermore it is impossible to get hold of anyone at UPS. As I am typing this I have been on hold for 15minutes to speak to the agent that sent the invoice. No response on numerous emails! Don't ever use them if you can avoid it!
