Mweb wrongfully canceled my telkom ADSL line now can't reactive it.

When I cancelled my internet service with MWeb they submitted the wrong date to telkom to cancel my the ADSL line and the line was cancelled a month early. When I called Mweb tech support they said they could not do anything until client services was open in the morning because the line was already canceled with telkom and they could not reactive it. Earlier that same week my internet went down and when I called MWeb they said the ASDL was suspended and that I needed to resolve the issue with telkom. I'm paying MWeb for the line rental and data, not telkom, but when I have an issue with the internet Mweb tells me I need to call telkom to resolve the issue? I am paying Mweb for a service. If there is an issue with the internet, Mweb should fix the problem, not me. What am I paying them for? If I had known that MWeb had no power to resolve issues with the telkom ADSL line I would have rented the line from telkom directly.
