BILLED FOR NOTHING!

I took a contract with MTN in May 2013 and it expired in May 2015... I called them in May to cancel it as I did not want to upgrade with them! I was told to call again a few days later because it abit early to cancel then.<br> <br> I called back on the 10th of June and they cancelled it.<br> <br> I was later advised that I owe R914 of which I paid in October if not mistaken because whenever I tried to call to get the actual amount its either I would be transferred from one department to another... It was worse in May when I tried to call them to cancel the contract because they were on strike so I eventually gave up on contacting them.<br> <br> Anyways last week I woke up to an email from their Attorneys (SHAPIRO SHAIK DEFRIES &ASSOCIATES) being informed that I owe R5653.14 including the R914.. <br> <br> When I call their attorneys I was told its early cancellation fees! EARLY CANCELLATION FOR WHAT BECAUSE I TERMINATED A MONTH LATER!<br> <br> last week I called MTN and I was told they not aware of such and they even sent me a paid up letter for the R914 meaning there is still a R4739 that is outstanding but they don't know about it because it doesn't reflect on their system.. WHERE IS THE 4K COMING FROM THEN?
