i too had my card canceled. when i called they stated that i was using it for business. which i did buy fuel but was not aware that i was not allowed to use it.l have had the card for 3 years and never was told anything about business fraud. i was saving my rebates and turned them in and all of a sudden there was a problem with my card being fraudently used i believe it is chases way of not paying out rebates. had i known i would not have used the card. i think if anyone is guilty of fraud it is chase.
