Has anyone had any luck upgrading an 811 to a 211/411 w/o having an installer bring out the box? I have called twice to get this upgrade and they tell me that the only way to upgrade is to have someone come out to install it. I really just want the box sent out to me and I can plug in the wires. Plus, I have "moved" and I don't want to change my "address" back or I will loose distants. If anyone has any suggestions let me know. It took 5 calls to finally speak to someone who spoke English!
