Using data whilst on WIFI

<p>Hi there,</p> <p>I have been a Vodacom customer since I have obtained my first cellphone many many years ago, and am a loyal customer, however, this is enough to ******* me off:</p> <p>I am constantly on WIFI, and not even using my phone (the phone is on the table). Yesterday, I received the SMS that states "you only have **** MB of data left". About an hour after that, I received another SMS to notify me that my data has been depleted.</p> <p>How the hell am I using data if I am on WIFI and my phone is on the table?</p> <p>This is enough to **** me off, as clearly this is a network making profit off something which isnt being used.</p> <p>As mentioned above, I am a loyal customer, but this is enough to turn me away from Vodacom.</p>
