As part of Visa's commitment to consumer protection, we have set up a process enabling banks to help you in unfortunate e-shopping situations, like when the wrong item was delivered and can't be returned, or when your flight is cancelled because an airline goes bankrupt.
The first thing to do is to contact the merchant, retailer, or tour operator to understand whether you're covered by a bonding authority or insurance scheme. If you’re not fully covered, if refund is only partial or if refund is impossible, you can request a chargeback.
