I'm not worried about it. They have no access to my money. They will need to go to County Court to get it, and provide the evidence to the judge, which they don't have. So as far as I am concerned they can go jump. Before that though, I will have some fun with it if they persist. I will need full ID, images of passports, driving licence etc, which need to be UK versions as they purport to be in the UK. They aren't, so that will be fun too. My guess is that I won't hear from them again. The credit card I used originally has now been reported as lost or stolen, and the number changed. So any attempt to charge it without my permission will be picked up by the bank and payment refused. All in all they can p*ss off.
