60,000 Credit Cards Numbers Stolen Online

For most e-commerce sites, 700$ for my personnal needs is okay, if I get frauded, it'll be ~500$ (balance) in the average, much less than if I'd use a 5K$ visa.

    Was the card a Visa or Mastercard? If so, call them, not you bank. Banks have had their credit card privelges revoked (and all cards cancelled) because of shit like this. I know Ford and Dodge dealers that have had the service centers shutdown and dealership stuff put under a microscope because of the same type of things but with cars. Also, go to the bank in person WITH ANYONE PERSON and speak to the big cheese himself. Be prepared with the reciepts. Know exactly how long you and your family has been a customer and how many accounts your family has conbined. Be nice but very firm. If they don't act, file a BBB complaint and contact you AG. They can't weasel out of it for ever.
