Impossible to get help

I currently have an active contracts with MTN which is in arrears. I have spent an exhausting period of time trying to make a payment agreement and at this point, I have been sent from pillar to post over this. Over the past four months, I have received different statements about the amount I am currently owing, with one outstanding balance being 12k plus and the other over 35k. When I called in last year to work out an agreement I was simply told that they would not help me with that and the agent hung up just like that. I sent an email asking for clarity which received quite a robotic response and no follow-up call. At this point, one agent stated that my account was handed over and another said that the information was incorrect. Out of the three contracts, one should have been paid up but at this rate, I have no idea how the interest was accumulated. I strongly believe that these ridiculous amounts would not have come up if MTN truly cared about assisting their clients. It's over six months later and still no resolution just accumulating interest and threats of being handed over. More disappointing than anything else was the consultant that I was on a call with this morning who told me that I knew that I would have to pay which was quite an ******** statement considering how long I have been begging for a payment plan. You can do better MTN SA.
