Why have a call centre?

Trying to do some follow up on my line move request 2 weeks ago. According to Telkom it should have stopped working at my old home and was scheduled for activation at the new premises today.<br> <br> Currently the line is still active at the old premises and I cannot seem toget through to anyone at Telkom. <br> <br> Phoning the call centre results in you pressing allot of button prompts just to get to a point where the automated response says. This call centre is experiencing high volumes and then disconnects the call.<br> <br> I will not be paying for the service at the old premises.<br> <br>
