afaik Europe doesn't have the same rules regarding chargebacks and it's much harder to successfully dispute a charge there.
Chargebacks only work the way they do in the U.S. due to regulatory requirements that the card companies allowed to go into law because they'd figured out how to profit any time a chargeback was filed.
Chargebacks in the UK are protected by law, where credit is concerned, because the CC company is a party to the debt they are legally compelled to return the money to you pending an investigation.
I don't know about the rest of Europe but here in the UK it's just as easy as the US and just as black and white.
