Paying for no service!!!!

I requested to have my line switched as we were moving. Only to find that telkom never installed lines to the unit we are staying in. After waiting a long time for an appointment, we managed to get one for the 10th of Feb( still being charged for adsl and telkom without any service) Telkom sent out a contractor that was unable to assist and said he will come back and this never happend. I have **** several calls to telkom, every time i wait for half an hour on hold with no success. I have been told they will phone back and this never happens. It is now the 18th of Feb, almost the end of the month paying for a service and for internet that i cannot use! This is unacceptable!!!
