Local police won't be remotely interested in this - small scale fraud (and I'm not suggesting this case is even fraud!) is all handled by action fraud (City of London police) now. I was victim of a bigger scam last year. They're still haven't got round to investigating
I would continue to chase them. It could well be a slightly disorganised small business who's made a genuine cockup. I've certainly been there in the past.
Since they presumably already know you have posted this on here I would suggest in the short term naming and shaming won't be particularly helpful.
