Horrible service from Call centre

Wanting to cancel my telkom line due to bad quality I canceled the adsl part with afrihost in under 5 minuets. When I cal 10210 to cancel the telephone line the first lady takes my details and transfers me to wholesale were I told here that, that was the wrong department after going through to wholesale they ask me what I want and transfer me back to the call center where it ring for 10 rings and the phone is put down on me. When I call back Im on hold for 20 minuets where a very arrogant agent answers when I tell him I want to cancel my line he keeps me on hold for 10 minuets were im told I have to wait 30 days for afrihost to cancel my line only then can I cancel my line. When I point out that this is ludicrous if i rent you a desk and chair and you can to cancel I take the chair back but not the desk and charge you for it he then put me on hold until I put the phone down.
