That’s horrible! I guess I’m pretty lucky because all my teachers filled out the recommendation on the same day I sent them the link. Never thought that teachers would refuse to fill out recommendation forms…
Right now, I think you guys should email the admissions at the schools you’re applying to, and tell them that your recommendations might come abit late. Then, ask the teacher to deny the recommendation request, and send a new link to your teacher from last year. Good luck!
