Terrible slow service

The staff at the courier customer services is pathetically disinterested in their jobs. They do not follow up on documentation required when their system says they are following up. On several occasions I've has packages that arrive in South Africa and it is lies at UPS for several day without them contacting me for any documentation only to be told it is required when I call them. I run a small business and delayed packages mean cash flow tied up. It really is a pity that they have this 'don't care' attitude.
