Who called from 3308642100

Caller just leaves a message that it is an important call and I need to call them back.

Calls in violation of telecommunications act with pre-recorded message.  This is criminal behavior.

WE HAVE IMPORTANT INFORMATION!

Obviously-digitally-produced voice left voicemail that said, "Hello, I'm calling about important personal business. Please call me back at 330-684-2100." No identification given.

Same thing, doesn't say who it's for or what they want, just "important personal business".  We don't have any outstanding debts, so it's obviously a wrong number or scam.  Looked up information online, but no e-mail address.
