Scheduled a plumber to come visit to do several jobs (c. £400 estimate, i.e. not a tiny job). Provided a full brief of the job and agreed time for visit. I made plans to be in the house at the agreed time. Plumber was a no show. On calling up, I was informed they had been busy. I am not impressed as they didn't take the time to call me to reschedule. Not very professional.
