Worst Service - Vodacom

I would like to express my huge disappointment with Vodacom in failing to address my simple issue. Both myself and my wife previously had a Vodacom phone contract. Both contracts reached there end of life and we decided not to upgrade or renew. We followed the correct process to stop these contracts. However, more than a year later the contracts still show on our ITC Reports as active. We have send numerous emails to vodacom, and not even once have we received a reply from any person at Vodacom to address our issue. How is it that we are not even answered. This is the worst service I have ever received from any service provider. I am Asking again. Could someone please contact us and attend to our issues.
