Telkom's poor services

I ordered a Fibre core deal from telkom 2 weeks ago with a free router and free installation. They came to install it but unfortunately we had a problem with our lights due to a sub station that burned and couldn't do the installation. The delivery man said to call him when the lights came back on to do the installation but our lights were off for a total of 4 days. When I called him he refused to answer and when we did get a hold of him, he was rude on call and put down the phone in my ear. The second time I got a hold of him he wasn't even there and his neighbor was there to say he was somewhere else and will pass the message along but still got no response. I called telkom directly and tried to find out what I must do but gave me the run around. They even said that my account was active yet I got nothing from them. No delivery has been made since. They also said that they were supposed to call me on the 27th September to schedule a delivery yet no one called on that day at all and that they were supposed to send a message to do my username name and password yet no message came through till Friday when I confronted them. I'm supposed to start paying the Fibre deal on the 5th of this month and I will not pay for something that wasn't delivered. Really wouldn't recommend them at all due to the carelessness and uncaring ways towards there customers.
