I feel your pain Watermeadow. Last May small extension being built at work, looked good, clean, tidy, workers. Asked if they knew a chippy - yes, his brother. Made contact. Didnt turn up for appointment, rang, got apology. Eventually came, quoted, accepted, handshake, to come in Sept. Didn't happen, nor October by which time he stopped answering texts and calls. Decided to use partners phone (thinking this number would not be in guys phone). Sure enough he answers, full of apologies, can't now do it himself but will send one of his employees round to look at job and also asked if we would mind if he worked over the Christmas /New Year period when builders traditionally closed. Said that would be fine. Chap arrives, looks, measures, makes notes and says he'll send quote. Nothing happens. Christmas/New Year now over, roll on Monday morning when I will be calling yet again!!
I don't really know how to find tradesmen when you're new to an area but have seen some people asking for recommendations via Facebook so may give that a go.
