Severly Bad Service

I tried to get my account disconnected since May 2015 and nothing is done. I was told it would take a month but it is still active. All i wanted was for it to be de-activated but all Telkom can do is to switch me between departments and not de-activate it to bill me more and more every month for NO SERVICE. We are now six(6) months down the line and it is still active. My husband wants to take Telkom to Court for *****. This is my last resort in attempt to disconnects, deactivate the account complete.
