MTN IS NONSENSE!

Hi.<br> Im writing this being an angry man. I loaded R60 airtime on my phone. Made a few calls. Then loaded a 300mb weekly bundle for a cost of R35. I was left with R24. Then all of a sudden my airtime had been depleted. When i called MTN customer care, the consultant (Tracy) tells me its because when you open more than app at a time MTN bills you your aiirtime and not data. Now when the hell did mtn change their billing policy and why were we the customers not notified of this? This is nonsense. I am done with MTN. Your service has gone down the drain. What a shame!
