Not Responding to any Communication Costing me

<p>I Moved Out of my old place in december and put in for a cancellation of that Line in february but have not heard any response to the email that i sent. and when i call they just say my accounts overdue and hang up. seem like telkom just wants to keep billing me for something where i dont even live any more . and the callcentre says that the cancellation department will call but none has called or even responded to any of my communication.. this is a ripp off</p>
