SAPO customer care non existent

Package is sitting in the dreaded SAPO Johannesburg hub without any movement.

Incomming International,JHB INT MAIL CENTRE (HUB)

Problem is it's impossible to get a response from the customer service department via email, impossible to call SAPO hub or customer service, local post offices are not willing to sit on the phone to their own company to find out when the package will be sent on. Just a big black hole.
