No Mobile Data. No Communication

I have been a client of Vodacom since Vodacom first started in South Africa. A few months ago we had to blacklist my wife's phone (which is under my name) the mobile data on her phone has been an intermittently usable, for reasons unclear to me. I have tried relentlessly to get this matter resolved but this past week my levels of frustration have reached new heights as I am completely unable to even COMMUNICATE with Vodacom using my wife's details. The irony of this lack of communication from a tele-communications company is not lost on me. I expect a quick and urgent response if I am expected to remain a client of Vodacom.
