Contract upgraded without my consent

<p>My contract expires in January 2017, that is what i was told by a call centre agent in 2016. She told me to call back in January if i want to cancell my contract. Today I called to cancel but to my surprise the call centre agent tells me I cannot cancel my contract as it has been upgraded, I did not authorise this and have not signed any paperwork for it. now they want me to sign an affidavit at the police station and send it to them and that will take about 22 days just to investigate . </p> <p> </p> <p>I can't get any reception on MTN where I am so I can't use my phone . 20 days I don't have as I need my phone . All Iwant to do is cancel my contract . </p>
