MTN disappoints once again...

<p>I had an internet contract with MTN which I cancelled a year ago. Yesterday i received one heck of an amount I am "outstanding". But I received an email that they received my cancellation in writing with a ref number. </p> <p>It took me 3 months to just get the contract cancelled at the branch La Piazza square in Klerksdorp. If they didn't loose my papers then they didn't know about the cancellation. After 3 months i eventually got my contract cancelled. I made sure by going to MTN in Klerksdorp almost weekly and every time they told me everything is done and cancelled, they even showed me on their system that my contract was cancelled. I don't have to worry about anything. But now i get this huge bill from MTN. Someone is not doing their job or is not interested in doing their job. </p> <p>What kind of service is this? </p>
