Probably not worth paying for a ferry to be honest.
For the record, I was in no way, shape or form suggesting that I’d go to their house and fight them.
I’d go and ask for it back and if they didn’t give it to me, I’d call the police. These people do these scams because they’re anonymous. If you turn up at their house, they’ll realise that they aren’t as anonymous as they thought and might think twice in future. I wouldn’t expect that going to their house would get my scope back but I would certainly go and ask for it. Police are far more likely to attend if you’re stood in front of the scammer.
Maybe I just watched too much Cook Report in the eighties?
