I'm heartbroken at what just happened

I spent so long trying to apply discount codes they offered on their website but those weren't applying. Then finally I see that there's a promotion that was giving me $400 back for trading in my A21 for the S25+ I wanted. But I was talking to customer support about the code S25SERIES2025 not working and then it hit 11:59pm est and now I feel so heartbroken and floored. I've been waiting since last year for a good discount but now I feel hopeless and so disappointed again. I'm legit crying because I wanted to be able to take photos to keep memories on a good phone but this is just so depressing I missed out again
