Incorrect data charges and false advertising

January bill (due 2015-02-28): There is a R505.73 charge for data usage which is incorrect.<br> History of SMS's/transactions<br> 2Jan: < 807MB<br> 6Jan: < 485MB<br> 10Jan: < 242MB<br> 14Jan: 1GB bought<br> 17Jan: < 735MB<br> 18Jan: < 489MB<br> 20Jan: < 243MB<br> 21Jan: 2 x 1GB bought (only one was needed but 2 requests were sent) *As i had 2 GB i used more<br> 26Jan: < 1GB<br> 27Jan: < 691MB<br> 28Jan: < 500MB FB bought<br> <br> *There was no period during which i was not covered by a valid data bundle so the R505.73 data usage charge is incorrect.<br> <br> There are now also additional data charges for Feb. I currently have a 500mb FB bundle. Which is not being used when exploring FB app on my device. <br> <br> The current FB app loads external sites in app, therefore that browsing should form part of the 500MB FB bundle but I am being charged data usage for browsing in the FB app. Do I also get charged for when FB loads an image hosted on another site in its news feed? Then the 500MB FB is false advertising.<br> <br> I carefully plan my data usage to ensure that I am always covered by a data bundle and when on FB bundle I only use the FB app on my device.<br> <br> It is ********* that I get charged data usage when I am always on a data bundle!!!
