UPDATE: He's blaming it on his phone.
On the night before, we had agreed to meet at 11:00 am (all done on RM Messenger as he lists no phone #) and I told him to confirm and text me his address in the morning. At 9:00 am, he texted me a "Good Morning" and after a few back and forth texts, he gives me the address and instructions to let him know when I arrive.
At 10:30, I text him to let him know I'm leaving and that GPS says it should be about 20 minutes. I text him when I park and then send two more texts and finally a call at 11:15, which goes to voicemail and I leave a message.
When I get home (11:41), I send him a message on RM asking what happened? He responds 2 1/2 hours later with a story about how he had broken his phone and is using an older one from a "few cycles ago" and that no messages were going out or coming in from "since around 9:30/10am this morning."
