Same thing happened to me, in fact maybe worse. I followed instructions on the e-mail... selected my note 7, upgraded existing with another Samsung device. My device isn't due until tomorrow after shipping Friday and my card was charged full process for the S7 + tax + restock fee. I can't get through on the phone and chat is greyed out, I have no idea what I have done at this point.... but it looks like I just bought a phone and still have a note 7. I am not on contract and always buy outright.
