Why does it take FOREVER to cancel an upgrade?

MTN Karaglen convinced me to buy the MTN Sky package, which I did not actually want. This contract does not meet my requirements. I entered into this contract on 2015-09-16.<br> The next day, I submitted the request to CANCEL the MTN Sky contract, and revert back to my old contract (MyTime100 with 2GB data recurring), reference ***.<br> Nothing got done, so I asked MTN Karaglen to check what is happening with the cancellation. I got a new reference number ***. Still NOTHING has been done about this request, almost 2 weeks later...<br> Now this reference has gone into \SLA Violation"- whatever that means?<br> It took you 1 DAY to get me onto this contract that I did not want. And yet"
