UPS South Africa has zero customer service!!!

UPS South Africa is without a doubt the worst international shipping company to deal with. Their agents have zero interest in helping their customers, do not respond to queries, have a different story to explain why my package is stuck in customs and what is required to get it out. I have spent more than 6 hours on hold - in some cases they have said they were forwarding me to another department and then went home at the end of the day, leaving me at home. Having experienced UPS in the USA, the South African operation is like on another planet. We have used Federal Express and DHL in South Africa and they at least do seem to care for the customer. I wish I could apply negative rankings here, UPS deserves a -5 rating. My package is now more than 10 days overdue, I have provide everything I was asked to provide and now I cannot even reach anyone anymore. Please do not use UPS!! The do not deserve any business here.
