Both promos require app authentication, so you should have received at least a pop-up dialogue. If you didn't, it could be that your browser blocked it, and therefore you never saw the authentication request.
Anyone who gets a rejection message should check their TopGuest account (if you might have one) to see if it is still active.
data point - the similar HH promo (watching the video) that I entered on 9/17 didn't post the 500 to my account until 10/3. this was a diff video so I tried it again - will see if I can "churn" this promo
tried the topguest one and it was accepted but the points didn't post instantly, will wait and see on that.
