Wanted to cancel contract but didn't want to and then MTN cancels it

<p>So December 2016 one of my MTN contract came upto the last month of the contract so I decided to Phone MTN to cancel it. So the person that I delt with said it would be done. So when I decide to see if it has been cancelled, then it was't cancelled. So I phoned MTN and I was on hold for the cancellation department for like 15mins and then I decided to put the phone down because that is rediculous to wait that long. So I messaged MTN on facebook about this and then the message just gets read and no reply so I complained again. Eventually I get a reply and then I reply back stating I might upgrade and the message gets read but no response. Now the contract is cancelled and now I can't upgrade it. This is pathetic service from MTN. I'm really dissappointed with them and I have been with MTN for nearly 8 years and this is the service I get.</p>
