Bad Service

For the past 4 days I have been struggling to get assistance with getting the pin number for my blocked sim card and all I get when I call the customer care department, I hear the recorded voice message stating that Vodacom has a high volume of calls, I mean this is not the service that I was expecting from Vodacom because honestly speaking Vodacom is really the biggest network provider. all I need is just the pin and Puk number for my sim card that's it.
