Unsolicited subscriptions and appalling customer service

Last night whilst playing a game on my phone, I got an Sms about being subscribed to MTN Gamer + at R3.30 a day! This was completely unsolicited!!! I immediately cancelled and when reported to MTN via their Facebook page, I was told to inbox my number. Once inboxed I was asked for a whole lot of personal information by a Kefilwe who asked me for personal information such as ID number, MTN Pin, Address, home/work number and bank name and type! When I responded saying that I refuse to give that information via inbox, I received a response about verification and how I should phone customer care.... I mean really MTN!! I understand verification, but no one in their right mind will give that type of information via inbox or over the phone!! I also do not see why I should jump through hoops to cancel subscriptions that YOU decided to subscribe me to without my consent!! Unsolicited subscriptions are NOT on and is blatant theft, especially when I already pay you for a contract every month and have to purchase more of your overpriced data because it doesnt even last. I cannot wait for my contract to expire so that I can port over to a different network. Its suchaabpity that I cannot add the screenshots of the terrible service received from Kefilwe to this review. I am done with you *******!!
