MTN SA is *****ing from its customers

Hi, MTN SA must stop auto subscribing customers without their knowledge, they deduct airtime in the process and one is required to unsubscribe. What about those who can hardly find they way around the phone, they only know how to answer and make a call. MTN SA is *****ing from its costumes, l am asking every customer affected by **** to share their experience and expose this uncouth practice. This practice is more common on free sim cards they often give out, there's nothing free - be careful folks.
