My airtime and data is getting used up at a ridiculous rate

<p>My data is getting used up at a ridiculous rate, just over the past few days i have loaded about 6gigs of data and about R500 of airtime. All of it has been completely depleted within that space of time. I called the MTN prepaid call center on 173 to let them know that something is terribly wrong but they keep telling me that its the internet that is depleteing my airtime and data.</p> <p>I have switched off all my cellular data with all my apps on my phone and yet still my data and airtime is getting depleted.</p> <p>I also have a WIFI modem that i use most of the day and i dont make many phone calls. Please can MTN stop taking advantage of its subscribers, what they are doing is **************** and should infact be investigated by the competition commission or the telecommunications ombud.</p> <p>****************!!!!</p>
