Each transport company tries to improve its service, its delivery times, and availability on a global level every day. The South African Post Office is no exception. Despite criticism of its commercial monopoly, the South African government maintains its position on maintaining control over it, granting a 25-year exclusivity permit in which SAPO becomes the sole provider of the service. This prevents the diversity of rates, various services as well as renowned trademarks, which must work directly with SAPO on a mandatory basis. This detracts from some reliability as a company, however not everything is gray, they have also implemented online services to ensure their customers' products, such as SAPO tracking which you can access from a browser or app on your cell phone as well as a call in which you can check the status of your shipment.
