MISSING DATA , VODACOM BLAMES OPENED APPS

<p>On the 23rd of May I received an sms from vodacom advising me of a network update that will affect services , In the evening that day I ran our of over 200 MB of data , on the 24th of May 07h00am I loaded 30 MB which got finished in an hour , I then loaded another 160 MB which dissapeard in seconds , called vodacom and spoke to ZANELE who first put me on hold for a long time and then told me I have apps open thats why my data went in seconds , I told her I do not have anything opened as I just loaded the data and checked my balance she still argued with me and said theres apps opened , My question is this even if I did have apps open how can 160MB of data dissapear in less than 1 minutes ? Also when I loaded the R50 airtime my available balance was R42.00 . VODACOM are ****** and they refuse to admit that they have ****** a customer and now I am afraid to load data .</p>
