Customer Service **** at SAPO and management

We have the RPA (Retail Postal Agency) in a small place in the Northern Cape. It is now two months that we did not get paid for service rendering. It is not only our RPA that suffers, but also the other RPA's in the Northern Cape. We report to Kimberley, but those people do absolutely nothing. They don't worry about us. This matter was also reported to customer service that is supposed to look into this kind of problems, but also they do nothing. Nthabiseng Mabogwane at customer service never came back to me with any answer. What is the use to contact customer service? They are just there for the money. Any one else have this problem with the Postal Agencies?
