The fact that they don't answer the phone should be a red flag that tells you how unprofessional and unorganized they are. Working for them would be even worse.
You should try to go in person
It's a holiday weekend so they probably aren't answering they're phones.Check back after the holiday and I'm sure you'll get through.If they don't respond right away keep trying.You might have to volunteer to get your foot in the door.
