Extremly bad service

On the 06/08/2015 I requested for my ADSL line to be relocated from my old address to my new one (Which is in the same suburb so my nr don't have to change.) on the 12/08/2015 a lady from Telkom phoned me just to confirm my new address. I was also told the a technician will contact me soon to make an appointment for the installation. On the 18/08/2015 I phoned Telkom to find out when the installation will be done. I was told that I was book for the 21/08/2015 which I accepted seeing that I had a date now. Late morning on the 21st I phone Telkom again to find out what time the technician will arrive at my house, I was then told that there is a technician working on the line and that he will ask the technician to phone me and give me a time more or less on when he will arrive at my house. 5 minutes later I got an sms from Telkom saying I was book for the 26/08/2015. I drove to the store to find out what was going on. the lady said that there is a problem and that the system only says that my installation is book for the 26th and she will ask the manager from the technical side to phone me and try to work something out. I am still waiting for his phone call.
