Data disappears, tracking use on phone statistics

<p>Hi,</p> <p>So my data disapears really quickly and so I have started to use my Cellular Statistics setting in my iPhone, showing how much data has been used by my phone both cellular and wifi.</p> <p>I have used 50MB this month (2 days) and just got a message from Telkom my data is finished. I get 1 GB a month.</p> <p> </p> <p>this has happened more than once and I want to know if I have the right to cancel my contract because Telkom is not keeping to their agreement.</p> <p> </p> <p>What else can be done, because there is always an excuse from their side regardless if we have proof such as what i have. Hard evidence on my phone.</p> <p> </p>
