MTN do not treat customers fairly

I have not often received such bad service or experienced such red tape in my life, I purchased 1 gig of data which was never sent to my device. when I queried it I kept being told sorry mam the network is slow. Bearing in mind every time I call it is at my own expense not free as I don't have a MTN device I can call from. Now I have to wait 4 days for the query to be resolved and no trace of my data, for all which I must pay in the meantime! All the consultants I spoke to don't really care about my problem all they say is that is the way it works and I must wait, getting irritated with me because I am complaining!!!! All I get told is that's the way it is and they can do nothing about it, MTN don't treat customers fairly. No remorse from them they don't subscribe to TCF
