Vodacom *****ing money

My data was depleted tonight. I quickly turned to my cellphone banking and purchased a bundle of 1GB for R149. The money was deducted from my account however my balance was 0.00mb and I had the notification to sign into the network. I then thought that the purchase was faulty as it has happened before and repurchased the bundle, this time 500mb bundle for R99. Again, the money was deducted from my account however my balance was still 0.00mb and I was still notified to sign into the network. I tried one more time, this time purchasing 250mb for R59. The money was deducted from my account yet again but my balance is still 0.00mb and I am still being asked to sign into the network. I rely on my phone for work and private purposes and demand either a refund or the data that I paid for to be loaded onto my SIM card.
