Being charged exorbitant data bill on blackberry

Vodacom charged me exorbitant data bill whlist still on BIS plan in December 2014 amounting to R1364. I did not use this data and dispute the claim. <br> <br> I have received feedback yesterday stating that nothing can be done from customer care as data service team claim that on the 29th December I used 615mb of data in 16 minutes. They claim that I accessed apples iTunes from my blackberry. What a joke. <br> <br> I have been asked to elevate this to customer care supervisor and manager level failing resolution, before starting proceedings with icasa.<br> <br> It seems that Vodacom has to resort to cunning and ********* business practices to make a profit. Internet is full of issues like mine......seems it's a Vodacom strategy,<br> <br> Please confirm that supervisor and manager cannot assist, so that I can start legal proceedings.<br> Ref number: S3-8WH3R-RPT69 ***~AJ5X<br>
