Vodacom trying to ***** from pensioner

My Daughter went to USA and I took over her data plan from her, to help her out.<br> <br> My son helped me to add a R50 limit to this data plan so that I don't go over that amount as I am a pensioner. <br> <br> It has been working perfect for the past 3 month and now all of a sudden in December I get a bill for R5500. When I tried phoning Vodacom twice, the ladies will just say it is a soft cap and you can still download.<br> <br> 1. Why did it work the previous 3 months<br> 2. What is the point of their call/data limit if it does nothing.<br> 3. How can a Limit just stop working in the benefit of Vodacom.<br> 4. I am not able to pay this and feel it is ******** from there side to try something like this.<br> <br> This matter needs to be resolved asap. PLEASE HELP!<br> <br> On a side note, trying to get this contract of my daughters name onto mine, was a nightmare. When logging into the vodacom site, I can't see any billing info for this number as well. Just get errors. EJB Exception:
