Account R8000 over limit set.

I have had a contract with vodacom for over two years already and my next contract only ends in 2017. I have set a limit on my account to stop myself from overspending. Every month I run out of data a few days before and my account to gets soft locked. Imagine my disgust when iget my account today and it's R9000.00. This is R8000 over the limit iIrt for myself. Every month iIbuy data to make sure iIcan stretch it put throughout the month and I am always conscious of my spending. I could not believe it when I got this bill. <br> <br> So iI phone vodacom customer care and they tell me that the soft limit does not work as I was previously told in store. Apparently the last session will not close even if the cap limit is reached. This is ridiculous as the only warning messages I received said that my data packages were completed. How can your system allow someone to go 8 times over their limit without atleast informing them that they have exceeded the soft cap limit. I was not even aware of the downloads happening ad one of my devices unfortunately connected and started updating through my phone. This seems like ****************. Your systems need to be fixed and iIneed to be reimbursed
