Who's subscribing me to services!!!!

I just recieved a message wich said my gamer + subscription has been renewed. What the hell I've never ever subscribed to something like that. You guys charge R4 A DAY!!! For a subscription I never asked for. I would like a full breakdown of what has been charged to my prepaid account. MTN you guys are a dishonest and ************* company. I recently checked my workers phone and she's also been paying R20 a month for services she never asked for.
