The builder with a long and very friendly history of an array of jobs, who has committed to doing my extension since before the planning, who then saw the plans, did a very long assessment of the property, came with a colleague who was to be involved too - and then stopped replying to messages. Messages are read. No explanation, complete ghosting.
A very friendly horse riding instructor stopped replying about booking lessons.
Some smaller examples, like a a gardener and a physiotherapist.
Absolutely 100% no conflicts and no payment issues ever.
Does that kind of thing routinely happen to others? Why won't they just reply to say no if they can't help anymore? Should I keep trying to get in touch?
