Growing impatient and considering canceling

Over the last few months we have had a problem with our telkom line. This also included their huge mess up where lines were crossed. We thought we would be compensated and not be charged the entire month because the error was on their side. This was not the case and we were still charged the whole months rental. More than 3 weeks ago we logged another complaint where we cannot make any calls out and no technicians have attended to the problem to date yet we still receive the bill to pay the whole months rental fee. Telkom is very quick to disconnect your line if you don't pay on time and bill us yet they lack actually rendering the service we are paying for. They can take however long they wish to sort out the problem and offer a service. I am utterly disgusted but the lack of service.
