60 day notice period!

I recently sold my house and at the start of July 2015 phoned Telkom to cancel my line (Voice and ADSL). I was told there is a 30 day notice period which is fair. However, a problem arose because my ISP is not Telkom.<br> <br> Originally I specifically decided to rent my ADSL line via my ISP and NOT Telkom so that they can deal with Telkom when things go wrong (which it did and which was then handled very nicely by my ISP). But, due to the fact that my Data line is with a 3rd party, Telkom could not start the 30 day notice period before my ISP \released"the line to them. So"
