One place where there is no help on the horizon is in fighting fraud. It's a different but related subject. Lots of venues and promoters lose money, as do ticket agencies, because of our inability to do anything if we have a credit card that's no longer valid. We're not even told that the card is no longer valid. By the time we find out, the show has passed and the money is gone.
For example, banks having a responsibility to divulge that the card has been declared stolen since the purchase has happened would be a great asset. We have to do it on our own. The credit card company provides us with no support whatsoever.
