I was scammed out of 1920 many years back for a pre-amp. The story is long / tortuous, but in the ned, I traced the cammmer down by searching for the same pre-amp under a different name and he took the bait... I had him / her on the hook. I even faked the evidence of bank transfer. I called the Action Fraud folks 10 bazillion times... no use. Police.. no use... Barclays Fraud - no use. I was in actual mail dialogue with the person looking to do the same thing again under a different name... He was "there".... but action there cam none. I feel your pain
