I received a call from this number, but they didn’t leave a voicemail. It seems like they're trying to lure me into ringing back—likely one of those dodgy scams you hear about!

I received a voicemail from them, but they didn't mention their company name at all. The voice that spoke was distinctly American and requested that I return the call regarding some sort of inquiry. It started off with a cheerful "Hey!" which seemed a bit odd to me.
