Billing charges and info communicated

I have been trying to query charges on my account since app 2013 and every time I call the contact center they cannot help me, I need to speak to disputes but to talk to disputes I need to cancel, which is something I am very happy to be doing. I have a charge being billed to me for DSL and 1gb data which I did not ask for, I canalled all internet connections when I moved home. How difficult is it to understand I just want a land line! Its costs me over 200 a month for this and I don't want it, not to mention the landline never works anyway! I got so tired of trying to get this sorted I stopped paying hoping someone would call me so that I get this dealt with, even the attorneys did not bother to answer my calls or my mails! The staff at Telkom branch Clearwater were not exactly helpful either, someone will call me they say, when? I'm still waiting for someone to call me to get the charges sorted out! Then I pay the account in advance and I get charged a reconnection fee which I do not want as I'm trying to cancel the damn account ! And interest being charged to an acc. due at the end of Oct, this needs to be reported to the financial board !!! Can someone please just correct this!
