My best, or should that be worst no call was from a bike shop in York I went to a few years back. Went in on my way home from work and spoke to the owner about him building a bike for me. Basic spec was a Giant carbon one, with dura ace group set. Budget around 2k. He took my details, and said he will call back in a couple of days with a price for me. Waited till the end of the week and no call. Called the shop and owner not in. So staff took my details and said they will get him to call me back. No call ever came. So I took my money elsewhere. Ended up spending over 2.5k on a more unique bike (was at the time).
