Worst Customer service experience

Its almost been a month now that i have been waiting for telkom to install a landline at my residence, You hold on the line for a ridiculous amount of time to get told they cannot find your order first of all. Apparently an appointment was made and no one from telkom confirmed this appointment with my wife. <br> <br> I would like Telkom to cancel my order and avoid calling in future to sell me any products. <br> <br>
