Loss Free Minutes

<p> I lost 437 minutes because I was not using them by the 21/08/2016. I am done with MTN. It was never communicated when I called them they said they sent a message to every customer which they assumed we got. My wife and myself are on mtn and we dont know about this new ruling. Calling does not help, they are so useless, I asked the agent so if you cancelled my minutes why do I now have 200 free minutes if I'm suppose to only get 100minutes , he could not answer me and offered me a reference number instead. I will be engaging with the Ombudsman. How can I get out of my contract as it expires in 2017? I paid for those mintes and can use it like I want to, it is not like MTN gives it to us for free. This is *****</p>
