Poor Customer service

The service we've received from Telkom in the last month has been terrible. We've been waiting for our ISDN line to be moved for over a month. I finally get an appointment for Friday, and the technician apparently shows but doesn't bother to let me know he is/was here but found faults. The customer service line is slacking. Most people don't have any idea what they are talking about and others sound like they've just been woken from a nice long nap. Out of the many different people I've spoken to in the last month i think there were probably two who were actually helpful. Very poor service.
