Hiring manager wanted to speak with me, but never replied to my email?

So I applied for an internship last week, and I got an email from the vice president of the company saying he wanted to set up a call with me. So I emailed him back asking if wednesday at 10 am was a good time for him. He never responded. Idk what to do. Do I expect a call tomorrow? Is it a rejection? Do I email him back? I don t know what this means

Try calling in the morning. He may be flooded with emails he hasn't even read.
