we scheduled for noon last sunday, I showed up and tagged him and waited 30m to no response. I then offered a period of time this Friday, which he said would maybe work but he didn't offer any specific time or show up/message me in the range I offered.
update: after the extension we scheduled again for 6-7pm -4 on 5/12. I tagged him during the range, and waited until 7:15 with no response.
