No warning/block

My wife took out a contract at Autopage which covered a data bundle of 2GB per month from Vodacom and included a Samsung Tablet. We were using the features on the tablet to monitor/manage the data usage per month. This we have successfully done for 22 months. In April we exceeded the bundle by as much as 500%. This was due to changes to the settings of the tablet which was done by accident. <br> <br> We received our account at the end of April and could not believe our eyes when we saw the HUGE amount. Surely Autopage or Vodacom should warn the customer every time they exceed their usage and especially when you reach 100%.SMS's and e-mails should be send to the customer. <br> <br> No individual will download data that costs R6000. <br> <br>
