MTN is *****ing my airtime for "data usage" despite not using MTN APN

<p>MTN, you are *****ing my money!</p> <p>I'm an Afrihost user and I use the Afrihost APN on my MTN pay-as-you-go simcard, but MTN keeps charging me for MTN data use! Your call centre confirms that the majority of my airtime goes to data, when I can absolutely confirm that I've not used the MTN APN in months.</p> <p>Every time I call the Call Centre, they say they cannot help me, and redirect me on a wild goose chase. 5 calls later, I've given up on your "Customer Service Champions".</p> <p>Every day I wake up to an SMS from MTN saying I used R4 or R5 on out-of-bundle data - I ignored these SMSes thinking they were part of your mindless spam SMS marketing.</p> <p>I was sure there was nothing to worry about after double-checking my APN is set to Afrihost's. However my airtime has been declining at a worrying rate, so I took to screenshotting my airtime balance after every phonecall and SMS to keep track of where the money was going. And now I can conclusively say that MTN is *****ING my money!</p> <p>Is this how MTN is returning to profitability after the Nigerian fine? By *****ing from their customers? So much for being "SA's Most Improved Network"</p>
