HK Maker Lab Interview

I'm gonna crash out. I heard back from them and received an interview invite and was supposed to do the interview later today. (They gave me this time option) Anyways the program director messaged me earlier that we are unable to do it since the application for this program ended yesterday. Like hello??? What does this have anything to do with our interview. Genuinely so mad cuz I had to sacrifice important plans for ts. I feel like I can't just let this slide.
