Your personal information isn't safe. DONT USE MTN

I received numerous calls from one number every hour on the hour for 2 weeks. Finally speaking to the person I was advised that its MTN wanting to sell me a phone. I opted that no one call me as I cannot take calls. Got horrible service when calling in, finally I spoke to Nomsanda, who then told me that I need to tell her who called because they have 3 different companies who they client. THEY GAVE MY INFO TO 3 COMPANIES WITHOUT MY CONSENT!!! I asked to called by a team leader as she was conveniently busy, I was told that Louise Green the tm will call me the next day. Still no call, I requested on 23/02/16 to be called between 13:00 and 14:00 still no call.
