TELKOM SERVICE SUCKS

I currently have a fixed landline at home as well as an ADSL line linked to it. I am trying to cancel only the ADSL line but no one in the call centre can assist me. They keep referring me to do the cancellation on line. When I attempt to do this online it only gives me the option to cancel everything and not just the ADSL line. How difficult is this to do? No one has come back to me since last week and I keep calling every day speaking to a different consultant explaining the story over and over.

TELKOM SERVICE SUCKS!!!!
