I had the opposite problem - we received a card that we didn't activate (basically, lapsed account, being young and too lazy to close it).
They let someone in the USA (we are in Australia) pay a Netflix subscription with it. This was new, so it wasn't one of those inherited authorisations that sometimes exist when a card switches over. So not only did someone get the card number from a card that was never used, they let the transaction through when it was never activated.
It took numerous phone calls to sort out. Every time we did, there was a rounding error due to interest, foreign currency fees, etc, which meant we still owed money despite the only transactions being unauthorised. The ladies in the Philippines were nice, but it was ultimately an annoying ordeal.
