Hi,
Sorry about that - did you just get the board, or have you had it a while?
Can you connect to the board via USB? If not, please could you try a different micro USB cable? It's amazing how many dead cables are out there (many power banks come with cables that don't have data connected).
While I guess there's some chance there may be an issue with the button, it seems unlikely that both the button and USB were broken and it still managed to pass the test.
I think even if you do get USB communications working, if the button isn't working as you received it, it's probably something it's worth replacing the board for though.
