I had asked a professor for a LOR, which he said he would, about a month and half ago. Now, it's the day before the deadline and still nothing. I have emailed him a couple of times but he has not responded to any of the emails either. I called, and he didn't answer the phone so I just ended up leaving a message. What do I do? It's too late to find a backup writer... It'd be helpful if he at least replied to my emails..but nothing..
