Worst service ever !

I took out a contract with mtn 2 years ago which should be expiring now any time soon. I phoned in earlier this year to ask a settlement on which my details could at first not be picked up on the system. I called again today, they found me on the system. One consultant (Evelyn) told me that my last instalment will be month end of September 2015 and I must call now so request cancelation or otherwise I will be paying again in October / November 2015. I was then given a number to call for cancelations which does not even work. I then called in again and was told by another consultant ( Mcebisi) that the contract will expire only in December 2015 and my Last deduction will be in January 2016. Now I am confused and stressed as it seems the people at MTN do not know what they are doing or they are trying to rob people from their money!! The last consultant I spoke to ( Mcebisi) gave me a number to call to request cancellation but once again I got pathetic service and the number turns out to be a fax line!! I am not happy at all and can't trust MTN. call me urgently *** or email [Email Removed] I have the calls that I have made recorded
