POST OFFICE POOR SERVICES

So my father sent me a package from Cape town on the 16/05/2018, he paid R350 to deliver the package ASAP. They advised him it take 3-4 business days for the package to arrive. I called Roodepoort Post Office on Wednesday and Thursday spoke to guy by the name of Milton. He advised me I should call Friday, as the parcel would of definitely arrived by then , and he took my contact number so that he could call me when it arrives. Now bare in mind all this time that I have been calling, they took my tracking number and said it is on the way. So Friday afternoon I call, and some Indian lady answers, she takes my tracking number, only to tell me Quote " Sorry the last scan was out of Cape town and nothing there after, so its probably lost" and then I said, "How can you say that so casually. I mean my dad paid a lot to deliver the package and I have been calling all week , and they told me everything is fine, package on its way" se said, " your dad can log a dispute in a months time " Just like that, pathetic excuse for a courier service!!
