Our number is listed on both the national an Florida do-not-call lists, yet we received a call from this number at 1:45 AM. When I answered, the caller hung up. I re-dialed their number and got an automated voice message mailbox. No idea who the caller is, but shame on you for calling and hanging up. If it's a mistake, stay on the line long enough to say so when we answer. If it's not a mistake, shame on you for disturbing hardworking people's sleep!
