Contract cancelation

My Telkom Cell Phone contract expired last year round about September. <br> 17 December 2015 I filled in a contract termination letter and gave notice to end my contract and put me on prepaid.<br> It's now 2 months and 2 weeks later and I still have a contract with Telkom as they refuse to cancel my cell phone contract. This makes me wonder whether they are ****** or ***********!!!<br> They keep saying that they tried calling me but can't get hold of me to ask me if I really want to cancel my contract??? SERIOUSLY!!!<br> This is after I went in to the Hillcrest store 3 times to cancel my contract filled in a contract termination letter and phoned Telkom customer service 5 times and gave one month notice as requested.<br> What more do I have to do to cancel my contract!!!<br> Each month they stall I have to pay for their incompetence, my contract should have been cancelled by the 17th of January!!!<br> <br>
