Nothing good to say about MTN

I was previously a Nashua client and was then moved to MTN when NASHUA closed. Everything has gone downhill since then. Firstly, I kept requesting for a limit to be set on my bill and was told this has been a million times but my bill remained high. I was only told two weeks ago that they can't set a limit on an anytime contract!!!!! I then asked to be migrated to a top up contract, I had more than R100.00 airtime and data on my phone but after the migration was done I apparently forfeited the airtime and data!!!!! Why? Where is it written that you will forfeit airtime when you migrate???? I have called I don't know how many times but this has still not been resolved.<br> <br> I will never ever take a contract with MTN ever again
