I'm actually surprised that they let me out too. The system worked during the winter, but once the leaves came back it wouldn't work anymore. They could make it work with two, but my landlord wouldn't let them put up another dish. I ordered from a local retailer and they worked with me to get me out since I turned around and ordered d* from them
First off never, never, never call and speak to a CSR. As is often stated in this forum you may get several different answers to the same question, and of course if they are the wrong answer you have no recourse if there is no transcript. Always use chat when it comes to resolving any problem that may ultimately cost or save you money.
I would do a chat and ask for the box to be sent for the receiver. If the CSR says it is not leased leave it at that. Save the Chat and e-mail it to your self, then print it and don't loose it. If an internal Dish audit determines that you should have sent the receiver back and you sell it you need to have a record that states you were told they weren't leased. Having said that even though they ask for the LNB if it is "out of your reach" you just tell the CSR that and if Dish really wants it they will send a tech for it.
I am surprised that they let you out of the commitment over line of sight, especially leaves, did dish install the dish to begin with? I'm surprised they didn't send a tech out to move it....
Good luck
