Cant cancel Telkom line

I am due to be moving out of my current residence on 30 June 2015. I have attempted to contact Telkom through emails, online queries and their call centre.<br> <br> I have been trying at various times over the past month. Only to have 30 Min + waiting times on the line waiting to speak to someone from their call center. I do not have the time to do this. Not once have I gotten through.<br> <br> More than likely I will now be liable to pay for the next month at least for a line that I will not be using.<br> <br> Needless to say I am rather displeased and find it highly strange that one cannot cancel a service with Telkom in an easier manner. I have done my research and generally the only solution is to call to the call center.
