I applied to a few grad schools and my top choice school hasn't responded to me. They confirmed they received my application and all my documents. I even got in touch with a professor who said she would be happy to take me into her lab. On the website, it says we should receive their decisions by the end of March, and right now, it's almost the end of May. I've tried contacting the admissions coordinator, left him a vm and email, contacting the professor, and also the people I was in touch with regarding my documents. No answer from anyone.
Did they forget my application? What do I do? I don't think I'll be accepted at this point and I'll go to my second choice school. Can I ask for my application fee back?
