Missed a Call for Scheduling an Interview

Hey everyone! I ended up missing a call to schedule an interview with them requesting I call back. I did so less than 2 hours after receiving the voicemail, but I wasn’t able to reach them. It’s been nearly a week and every few days or so, I’ve tried calling again at different times, but still haven’t heard back. Is this common? And do I have anything to be anxious about when it comes to not calling back sooner? I was excited when I got the voicemail since getting this job would help facilitate a move, so I just want to make sure I’m doing everything I can while not going overboard.
