Data balance unavailable

For 4 weeks I have not been able to see the data balance on my computer when I click on 'check balance\. I have sent 3 emails to them and not one reply - very rude and discourteous. Can someone please tell me when this is going to be fixed or don't they care. I have been to 2 Vodaacom shops for help and they say this will be fixed SOME TIME.<br> And when I bought new data a week or so ago I received a message that it was installed and would expire on 1/3/2015.!!!!!! Don't they even know what year it is and that a new data purchase only lasts one month."
