Horrible service!

I am helping my parents to install their fibre, as I have been staying here and had fibre previously installed, when I left to my new house I said id help them set up their fibre. So I phoned 3 days ago to set up their fibre with Metro Fibre through Mweb. I told the sales person that everything is already installed and even gave her the Serial Number of the fibre box. I also told her that I have a router and all they need to do is activate it. Its been 3 working days, I phone back and ask them what the state is, they say no they have to send a a technician.... How in the world do they need to do that when everything is good to go! All lights are burning! They just need to switch it on! So the lady says they captured the wrong details! I am sick of waiting for their excuse of using working days! Somewhere in all these ISP providers they are trained only to sell and not to capture the correct data! Horrible service!
