Cannot cancel fixed line

I logged onto the Telkom website to cancel my ADSL and fixed line that was together as a promo. About 2 months ago, the ADSL has cancelled but the fixed line was still active. I found out it was still active so I went online to cancel the fixed line, but the only selection I could make to cancel was the ADSL promo, when I select this it shows that it is already logged. So the website is not updated to show my ADSL is cancelled and I can still cancel the fixed line. But I am also not happy that the promo deal did not cancel both the ADSL and fixed line. I just want to have the fixed line cancelled but cannot do this online. I was told in store and with the contact centre that this must be done online
