This person emailed me expressing interest in a car I'm selling and asked that I call them. I did so twice and the call went straight to voicemail so I replied to the email asking for a good time to try to call back. A day later received a few emails apologizing for missing my call and asking that I call back at a specific time. Got an answer but the person hung up immediately after I asked to speak to the person I'd been emailing. Calls went straight to voicemail thereafter, and the email address was no longer valid through craigslist. Glad I blocked my phone number.
