MTN caller Tunes

<p>I am being billed for Mtn caller tunes for the past year without subscribing to this service. I have tried cancelling the service for the past 6 months but have been unsuccessful. I have been told to sms stop/cancel/ no to 4100 after which the service would be cancelled. However the subscription keeps being re-newed.</p> <p> </p> <p>It seems like this is just a way of forcing the service onto clients without their consent and *****ing the subscription fees to increase their profits.</p> <p> </p> <p>MTN "s service really sucks</p> <p> </p> <p> </p> <p> </p>
