Voluntary call limit Misinformation

I placed a voluntary call limit on my RED VIP package (early 2015)<br> <br> On 30 May 2015 I bought a Macbook so had to download stuff, bought 2 5 GB bundles .<br> <br> I was downloading stuff but line did not disconnect when it went over the limit !!!!! <br> <br> So last month my bill was R 7500 !!!! I placed the limit to prevent this kind of thing from happening !!<br> <br> Also: Only the fifth \operator"could unlock the line and apparently the line will not lock if in 1 session!!!!!<br> <br> I find the huge bill very unacceptable<br> """
