Cannot get disconnect confirmation

Over the last two months I have tried to give notice to disconnect my normal residential TELKOM line in 4 different ways: by going into a Telkom store (they say it can't be done there), by emailing (reply error mailbox is full) and by phoning. After no luck with these channels I tried their Facebook page. They have rep**** twice that \Your query is attended to & feedback will follow."After almost a month since my Facebook query and two months after my email attempt"
