After a couple of weeks from my last text to him,I finally got a response. He was very apologetic and said he'd call me the following day and explain the situation.
Never got a call.
But he did text a few days later. Saying he planned on sending out refunds plus a machine (when they're ready), which is getting a complete overhaul.
I'm not holding my breath. If a refund and/or machine shows up in my mailbox, great. If not, lesson learned.
