Worst service ever!

I'm so disgusted with the service level rendered by such a big company! How pathetic that they don't even know what's going on in their own domain. And every enquiry that I make I get put on hold for an endless amounts of time. Which tells me that their staff is not even properly trained to do their jobs. This is my second month using Telkom services and I've been having endless issues, only to be told that the line I'm being billed for isn't even my own and I have to pay for it! The call Centre directs you to the walk in centre and the walk in centre directs you to the query centre and the query centre directs you to the billing department. What the hell kind of putrid service is this?! Does anyone even know what they doing??? To top it all off, the person I spoke to yesterday confirms the following that I'm being billed for a 4mbs line which has been cancelled, I'm also being billed being for a 10mbs line separately which has not even been linked to my telephone number. How does this work?! I was promised that the billing department will call me this morning to get this mess sorted only to find out that the billing department is closed today when I called back this morning to enquire why my WiFi is offline. To make things even worse when I asked to speak to the manager I was told that his too busy to come to the phone and that I should call the sales department,yet again to sort out my problem. For someone who has only been using your services for not even two months your first impression of your company is that you don't give a **** about your clients and that your business is souly based making money out of us for your poor services rendered.
