bad service and ripping me off

at around 16h45 on the 20th march i bought airtime voucher vaue of R10.00 , at 16h46 i recieved an sms that i have recieved a WOW BONUS BUT NO AIRTIME. I bought that airtime for a specific purpose as i had an emergency that i had to attend to. i called customer care to enquire and i was told told that they cant see what happened to my airtime, i then asked to talk to a supervisor, they took my name and informed me that the supervisor will call me back. i waited and nobody called me back. i called customer care again and was told the same thing again. I called the third time again the same thing ,this time i was given an email adress [Email Removed] still no one contacted me or rep**** to my email. i called again today and spoke to a useless individual by the name of Nkanyiso who told me that my air time was used by internet even though i did not log into any internet.<br> i have been a loyal customer for MTN since 2002 using the same number. and i am really disappointed about this treatment i am getting. i want my airtime back please and i do not buy the story that \i used the internet for less than a minute for R10.00 airtime???"
