Unfortunately I was given a 12-3 window so I took a half day at work. 3:20 still no call no show, called the office and they told me they'd ask the plumber to get in touch. 3:45 I called the office back and they told me they had a miscommunication about my appointment time (which I had repeated back to the operator for confirmation when I made the appointment specifically to avoid.) They still had no ETA for the plumber so I cancelled.
