That’s why naming and shaming is so important to flush all these arseholes out! Word of advice, next time get 2/3 quotes off different recommended spreads and don’t just go with the cheapest!!2 days, and I agree if you look for problems you'll find them but you really didn't even need to shine any light on it to he honest. Natural daylight was enough. Lesson learned I suppose. I'll know prices next time, but its frightening to think these sort of 'plasterers' exist regardless of how much they charge.
