Telkom, not a company of their word

An application for a new line installation was made on 20 Sept 2017. Was i formed that the line would be installed on 26 Sept 2017. Nothing happened. On 27 Sept 2017 a follow up was done and i was rudely informed that the technician phoned and did not get ahold of me. No evidence of this call on my phone. He also claimed that there was no one at home to receive him, the gate was closed and he left. This is not the matter, there was someone expecting the technition the whole day. There is a door bell at the gate and was not used. I was then told that the matter will be escelated to a higher level. To my disapointment when phoning today, i was told that my installation is put at the back of the line and i will be contacted for a new date of installation. The call centre opperator, Sinusiso can not speak in a soft and calm voice as he raised his voice to me a as a customer. I still have no line and no commitment for a line.
