My wife used eat24.com earlier this month while visiting our daughter in Atlanta. Then suddenly we have been barraged by illegal use of our credit card in the last few days. As we investigated, we also found multiple charges against our card on the same day (while in Atlanta) - which they did NOT do. However, not having the receipts, there was nothing we could do...
Avoid them like the plague! We had the credit card cancelled. Eat24 was the only charges that have been made on that card in the last 4 months, so I don't think it's a large leap of faith to be assured that's where the breach started.
