No service telkom

On the 11/06 of this year I canceled my adsl line. On the same day I got a confirmation email from telkom stating they acknowledge my email and a consultant will contact me within 7days. Needless to say I did not get a response. After numerous attempts to reach them I finally got a hold of them, only to be told they will escalate the quary and someone will call me back. First of all why must someone call me when I emailed my cancelation? Why must I now pay for services that was supposed to be suspended but due to their lack of service I am still responsible for it? There is just no service from telkom, they make it nearly impossible to cancel your service.... Here I am still waiting for feedback, still responsible for service I went about the right way to cancel!
