MTN unable to sort out billing issue since October 2015

<p>I have been complaining about being overcharged by MTN since October 2015 and MTN has not given me a satisfactory answer as yet. I left for Australia in June 2015 and have not used my MTN sim card full time since then, only on the weeks I was home. I would understand why I was overcharged for June as I had overused my credit, but the rest of the months, I have no idea why. I set up a limit in April 2016 and I was overcharged this month as well. I have been chasing MTN to get an answer but they are not willing to address the fact that I was not using my sim card when I was in Aus and wasn't roaming either. It has been frustrating following up with them, even though I have escalated them last week to their escalation department, ICASA, but nothing has developed from this.</p> <p>I am more than willing to move on to a much more efficient service provider that values their customers complaints. All I want is to sort out this billing out. In my mind, the overpayments should be used to cover the other months that are remaining in my contract with them.</p>
