Home Disconnect poor quality of service

Poor billing system. Billed me and suspendef my service because I refused to pay fof setvice I never ordered/ requested. I keep being billed for things I fo not know. I started service with them in August. Was billed R1100 which included services I never ordered. When I questioned was later told it was already billed for. They then threatened to suspend my service unless I pay the R1100 which I did. They promised to reimburse me. End of August was now billed R992.03. I questioned it and was told they will correct. Before they corrected they suspended my service. I sent tbe proof of payment for the R800 I paid. Now they say I need to pay R2203.03 with no explanation. My service been off since Friday.
