STILL BILLING ME A YEAR AFTER I CANCELLED!!

Last year this time I chose to switch to MTN due to poor service and high billing from Vodacom. <br> <br> In early January 2015 I ran around after Vodacom to attend to the closure of my account which was not an easy exercise. <br> <br> After I had cancelled my contract, I was told one more payment would go off my account at the end of January 2015. Which it did, whereafter I placed a stop order on my account. <br> <br> On 26 January 2016 I received a \warning"letter requesting urgent payment of an account from a year ago and threatening disconnection. I cancelled my contract so I didn't have to deal with Vodacom and their useless call centres. Now I find myself fighting with you again! <br> <br> Today my attempt at calling the call centre proved that there is no change in your service"
