Case closed with no update or feedback

<p>i logged a case about my all network data being used up instead of my night surfer. i spoke to a gentlemen by the name of Yanga on the 11th and called again , called today for feedback and i was told that the case was closed. a lady did call me with what might have been the problem but nobody came back to me with solid feedback as to why the incident happend or how they were going to take care of it. i need my data back somehow. cell number linked is ********** 155</p>
