Data bundle used in wrong order - THEFT

I have two data bundles active, with different expiry dates. Here is the usage history for yesterday 2015-10-21 (I monitor this myself via the website as Vodacom provides no way of reporting on it):<br> <br> 2015-10-21 07:00<br> Data 3 GIG (1.86GB remaining) expires 2015-10-22<br> Pay Once Data 2GB (0.34GB remaining) expires 2015-12-11<br> <br> 2015-10-21 10:00<br> Data 3 GIG (1.86GB remaining) expires 2015-10-22<br> Pay Once Data 2GB (0.21GB remaining) expires 2015-12-11<br> <br> 2015-10-21 13:00<br> Data 3 GIG (1.86GB remaining) expires 2015-10-22<br> Pay Once Data 2GB (0.19GB remaining) expires 2015-12-11<br> <br> 2015-10-21 16:00<br> Data 3 GIG (1.86GB remaining) expires 2015-10-22<br> Pay Once Data 2GB (0.08GB remaining) expires 2015-12-11<br> <br> As you can see, Vodacom is deducting from the bundle which expires on 2015-12-11, even though I have a bundle expiring 2015-10-22 (today) with plenty of data remaining.<br> <br> The net result is that I have to top-up now, even though I have almost 2GB remaining on my 3GB bundle, as it will expire shortly.<br> <br> This is really sharp practice by Vodacom - bundle should be used in the order that they expire!!!
