Called me twice while I was sleeping (not their fault; it was at a time when most people would be awake, and my phone was silenced anyway.) They left a message but didn't say anything; the message was about a minute long, and consisted of what sounded like ambient noise from a call center, combined with the operator breathing. Maybe he didn't hear my voicemail answer, so he was still waiting for someone to answer.
