In the building trade, as in many other sectors, a satisfactory outcome is dependent on many factors other than whether the tradesman is good at his job. For instance, a customer who cannot describe exactly what they want, does not fully understand the implications of what is being described by the tradesman, does not really know what they want, does not appreciate the 'unknowns' in building work could (in their mind) feel perfectly justified in being aggrieved by what they feel is a dissapointing outcome. I'm not saying this is the case for the OP at all, but can be a factor in general, so personally I tend towards not posting negative about a specific tradesman unless it's blatant piss-taking with no scope for their having been any misinterpretation. I've recently had a negative experience with a builder but I'm trying to resolve it rather than take revenge via the EDF. I think loss of work for a tradesman is a serious problem and all too easily done with an anonymous throwaway comment on the internet. This may please the poster in the sort-term, but have significant (and perhaps comparatively unfair) consequences for the tradesman. I worked several years ago as a self-employed handyman in ED and in Wiltshire and when working on repairs to houses you're often uncovering really bad previous work and some people are just not prepared to debate changes to approach to the job, overrun, extra cost and having to do a repair before you can do the job you were taken-on for. It can be a bit of a minefield for both sides.
