Installation done poorly

On the 4th of June Telkom came to install a new line at our residence. The technician didn't set up the router we supp**** correctly which resulted in me having to reenter the details that Telkom provides into the router just to get an Internet connection. This should be basic knowledge for technicians when installing a new router no matter the brand. We then asked that they come back an move the router to another Point in the house to which the technician said that we must call a friend to run a cable through the roof. I could do this myself but the main issue isn't even this. Since day one we have received below 1mb download on our 4mb line and on a closer look at the installation at the wall we have discovered that the line box that comes in is hanging off two wires and just poorly installed. We've logged complaints but no one has come in to attend to our needs and last response we got from Telkom was it's all fine there side. This is not professional and as someone who is in the industry I expect so much more. I've logged another complaint for the line not syncing and I surely hope you get back to me asap.
