Systems don't work the way they're supposed to

Asked Vodacom to implement a limit on my account, I am told that it's done, but they can't guarantee that it will work. What's the point? Ask Vodacom to inform me as I get close to the limit. Again, I am told that they can't guarantee that this will work. What's the point? I asked the consultant. "Technology" is all that she said... You guys are the fastest 4G provider in South Africa, surely you can figure this out? I am told that the only way that I can add data or airtime is to do it online or on the app. No dice, as I, the main account holder since beginning with Vodacom, am told that I am NOT the main account holder??? The Facebook team says, use the Vodacom website. Where do they think I went onto?

The sheer incompetence of their systems astounds me. It took 2 months to get 2 itemised billing reports from them...

What is happening Vodacom?
