Canara Bank ATM Fraud?

If your card is eaten by the machine you generally dont have to worry about fraud. You did the right thing by advising the bank straight away. They should give you a file number which allows you to verufy that the lost card has been notified to them at a specific time and date. After notification you are less likely to be responsible for fraudulent transactions. I would complain - get a complaint number to make sure it is not simply forgotten and always ask for the name of the person you are speaking to.
