MTN Devious Marketing Strategies

Marketing emails and MSM: MTN keeps sending marketing spam for games and other stuff that will cost between R2 and R10 a day. Many of these msm are designed to pop up over the keybord, when one is busy on the phone, with the chance of pressing their OK button very high and thus accidentally having to enroll for expenses not wanted. Their marketing messages come through any time of the day or night, despite repeated requests to stop them. MTN provides the option of switching off marketing emails and MSM, but none of the option are working. Nor it it working to phone them every week and ask to stop their spam. I find this kind of marketing abusive, intrusive, and ********* and have asked several times to be removed from marketing lists, to no avail. When getting a contract with MTN you sell your privacy and peace.
