I would like to commend Sifiso who was not only patient and helpful, but for the very first time I got one of MTN's call centre agents that knows how to do their job right.
As mentioned so many times on this site and other forums their are numerous flaws with MTN's administrative capabilities, but today I am happy to report that I found that one shining star that not only sorted out my problem (should rather read MTN's problem) immediately.
Well done Sifiso for doing your job, but doing it in a manner that is actually making MTN look good for a change. Judging by other comments, MTN doesn't need a turn-around strategy, they only need a hundred more people like you to resolve issues first time correctly.
