Termination a 24 months contract is impossible since October

During the month of October I contacted Cell C cancellation department by dialing 084143 spoke to one of their consultant/agent she informed me that my contract will be cancel automatic after the deduction on the 17 November but today when I contact cell c again to verify if my contract was cancelled the guy that I spoke to Pina (WHO EVER HIS NAME IS ) told me that the contract will not be cancel this month it will be only be cancelled following year on the 11 January 2018

And according to Section 14(2)(c) of the Consumer Protection Act 68 of 2008 (CPA), service providers need to provide you with 40–80 business days’ written notice or “any other recordable form” of the fact that your cell phone contract is coming to an end, thereby giving you the opportunity to cancel the contract on time ( I didn’t receive any call but I called Cell C cancellation department to inform them during the month October 2018 to cancel my contract as I have paid more than 24 months towards 24 months contract agreement)

I didn’t knew up until today why the agent I spoke to during October she didn’t offer me an email where I could sent my cancellation letter she told me that it is been done telephonically now am getting a difference story must I go to the police station and open a case so that cell c could provide the telephone records held asking for the termination of the contract I haven't been using their data and airtime since January 2016 until this present why cant they just terminate my contract as i was the one who didn't benefit
