You have sat service but switch to a land based service. Who is responsible for removing the dish? I can tell you it's not the sat provider.
You just bought a new house and want to make the exterior of your old house as aesthetically pleasing as possible by having the dish removed. Who removes it? Again it's not the sat provider.
I agree with you here. The homeowner is responsible here as it is their choice to make those changes. My issue is where the installer puts the dish where they deem fit and then later, instead of servicing it, decides to just install another dish. So if in a year, the installer comes out and decides that the second dish is not serviceable, they just install a third dish?
Even if the installer will not remove the dish themselves, I believe they are responsible for the cost the homeowner would need to pay to have it removed.
