I feel for you ! I’m in NZ but it’s much the same here, people talk the talk but rarely make you feel over serviced. A lot of what your saying comes down to having knowledge of an industry in that the guys doing the work in the past would just no what needed to be done. I go into hardware shops now and kids are serving you who have no knowledge of what they are selling not only that don’t care. It’s funny here but talking to guys it seems to Be in every industry and the guys that put an effort in are deemed exceptional ! Good luck getting it resolved
