Unfair suspension of line

I cancelled all services on Telkom on 31 October 2015, did the whole month notice period and then assumed that EVERYTHING would be cancelled as I requested. But since end November I get billed for the exact services I cancelled.<br> <br> The more I try to explain to customer services that I will not pay for something that is not my error, the more I hit a dead wall, with being transferred back and forth between departments.<br> <br> With this being said, the Telkom line in question has been unfairly suspended due to non-payment. But I haven't paid for something I cancelled and don't want or even use.<br> <br> Everyday I get a response back that I am a priority case & that someone will get back to me soon, but a week later I am still waiting for someone to get back to me.<br> <br> I am terribly frustrated as I do have a new ISP, pay for their service but get suspended by Telkom when I do not even have anything with them. I need to get the line back up as I rely on the line for work purposes.<br>
