Lost Data/Data Missing

<p>I have had data problems since December. In December I received a Invoice 4 Times higher than my normal spend. When i Complained they credited my invoice with a substancial amount as a goodwill gesture. If there was no fault on there side , why drop this so quickly.</p> <p>I requested a detailed explaination of my data usage and they could or would not supply that.</p> <p> </p> <p>Last week Tuesday i received my montly data 3g. On Sunday when I checked my data, I only had 400mb left.</p> <p>I find this very unliklly as I use wifi at work , and only do Facebook/watssapp and some Deezer after hours.</p> <p>I did log a fault , but have not heard anything back.
