Did you turn on the smartwatch?

AFAIK Amazon is able to check for S/N going online.

If after june 27 your claim is declined :

Just call them and say that your roommate opened the package and he forgot the watch in his room or find any other bla bla

Or say that you bought it for your roommate and he took it with him and went on holidays.

Convince the rep that you've been wrong, if he tells you that they sent right item just SAY YES i was wrong sorry bla bla

Wait 1 week, call them back and say that the watch is defective or not that good and you would like to return it

FTID ( i won't recommend it) or legit return to get your money back.

Make sure to record the return, Amazon now became really bullshit

Even for legit returns they will say " its was an empty box"

If they ask you for a PR just do it.

Good luck
