Telkom service should be minus 10

Telkom has offered us a Fibre package in July which we accepted. Vumatel came in and installed the Fibre line for which we had to dig our own trench for lines to be laid. Now Telkom keeps sending us from pillar to post for numbers which we do have and apparently "someone" has cancelled our packaged 3 times. If they can't answer us they simply cut the call. It now that we are trying to move to a new ISP that we need to pay Telkom to cancel but the previous Telkom rep told us we can't cancel a cancellation. So we have vumatel installed but can't do anything. Their service is deplorable.. They ask you to call a dept to get something done and that dept tells you to call that same dept back and so forth.. Sale tells u to call billing.. billing says call sales aghgghhhh.. Why can we not rate anyone with a minus.. Telkom will get minus 10 for service.
