Booked a plumber a week in advance as it's difficult to get time off work. I was told a plumber would be there between 12pm and 4pm, but they would call when they were on their way. Hadn't heard anything by 3:30 pm so I called them and was told the plumber couldn't make it but that they could reschedule. Incredibly frustrated that I took time off work and they couldn't even call me to let me know they weren't going to show.
