Vodacom/Mondo misadvised

I was advised by Mondo I will only be paying for the data bundle end of the month with my account. When I phoned to activate the sim I was told a debit order would go off today with activation. I disputed this as I was not informed off this. I contacted Mondo they listened to the call and came back to me and said I wasn't informed indeed and they would be covering the initial debit order. I phoned Vodacom and they won't release my sim although Mondo rectified the problem. I now sit without data and have to incure extra costs to get data on my phone and I think Vodacom should be liable for these data costs as they are not interested in resolving matters as soon as possible and take their time. They won't even get a consultant to phone me back today I just get told to wait 3-5 days. This is unacceptable.
