Unathorised Debit Orders

This is absolute ********. And there is no nice way to put this. Telkom... seriously... get your act together! When I called to enquire about an ADSL line in November I was told that I would be charged R189 a month for the ADSL, and R695 for installation. At the end of January I was debited R900. According to my calculations that is more than December prorate, January and the installation. I have now been debited R800 again, and the explanation to this is ********. I am now being told that I must pay R400pm for a phone line, then also ADSL. I understand I need a phone line, but why am I being charged for voice calls when I don't use the phone at all?! And now I am being told I must pay prorate incase I cancel?!!? Seriously Telkom... I want to listen to my calls to you to prove that I was NOT told about all of this!! If someone doesn't rectify this today, I will be taking this further legally.
