That part was opinion. You're trying to have your cake and eat it too.
I am certainly not trying to have my cake and eat it too. This week when I called dtv for the swap I was fully expecting and had planned for dtv to tell me I had to return the h20. I never even asked if keeping it was possible. I knew the answer. The rep volunteered it did not have to be returned. When the rep said that I was shocked and spent the next 10-15 minutes making absolutely sure the rep understood what I was saying and I understood what the rep was saying. Since I knew the rep was wrong, I had the rep write the note to the account and then read to me the note. I made some clarification changes to the note that the rep agreed to and then had the rep reread the note to me again.
I learned a long time ago what a rep says, promises, guarentees over the phone is worthless. Nobody can prove anything. If possible, you must get the rep to record the promise, guarentee in the companies system so that a definitive record can be recalled if necessary.
Please realise, the h20 box that would be sitting on a shelf for all time is OWNED and has VALUE. It is not a worthless leased box that dtv may or may not want back in the future.
