R2002.00 charge for Netflix streaming for 30min!

<p>I was recently watching Netflix, and decided to stream through my iPhone. Within 30- 40 min of me starting the stream, a bunch of SMS's came through, first saying "You have less than 248mb of data..." and within a few seconds, 10 more followed and I got a notification stating that "You've used out-of-bundle data to the value of R2002"!</p> <p> </p> <p>That's ridiculous, and It won't be settled on. Vodacom is always robbing people.</p> <p>Please can I get a resolution on this???</p>
