Doesn't really make sense does it?

Hi, I am trying to remain calm about this because it seems a little insane to me. let me explain: I am moving into a new property, the landlord of my old rental property wants to keep my fiber line and router and and and so basically she wants to keep my setup and use it for herself on the same package. So we contacted Vox and did a change of ownership form and sent it through. We were then given feedback to say that a transfer of ownership could not be done and my ex landlord would be charged a brand new setup and installation fee of R999.00 + R1710.00. I cannot understand how this could be because everything is already in the property - the router, the fiber, the package. All that needs to happen is you need to change the owner of the package to her name and not mine. So I phoned Vumatel who would supposedly be charging the R1710.00 to stare at an already installed fiber line (my assumption) and they said that they woulnd't charge for installation because the line is already installed - this makes perfect sense and is what I have been saying all along. Now Vox on the other hand is still going to charge the landlord the R999.00 fee for setup? Howcome? Does that mean you will pocket the router money because my landlord has my router already? and charge her R999.00 for something that is already done? Is this the way you treat your existing client base as well? I don't think you realize that your actions will affect my bank account because I will be in effect paying for 2 fiber lines soon enough when my new line is installed? Please could we all think out of the box on this one - if all the moving parts are already in place why charge for a new setup ? This seems like a money making **** if I am honest. Please could you assist with clarity on the matter.
