In the last 2 days, 2 friends have told me that they had fraudulent charges on their credit cards. In the first case, his bank called him and asked about an $800 online computer purchase. He did not buy a computer recently so the bank cancelled his card and issued him a new one. Now he has to scramble to write checks for those bills which were usually paid automatically with that card. Not fun.
In the second case, she was casually checking her card statement online and saw $300 worth of charges. This was alarming but not enough to cause her to call right away. It was 11pm and she decided to call first thing in the morning. She couldn't sleep though and got up at 3am to check her statement again. The fraudulent charges were up to $4,000 now including airline tickets to Holland, Turkey and Kosovo! She called right away and got the card cancelled.
The first card was from a bank who called their customer when the charges looked abnormal. The second credit card was from an airline and, well, I guess airline tickets to Holland, Turkey and Kosovo don't look out of the ordinary to them. Or maybe they weren't monitoring it at all.
I guess the tip here is to check your statements often. I usually check mine before the end of the billing cycle so that I am not surprised by the amount and just in case I need to shuffle money around since I have more than one bank account. Of course, credit card theft can happen to anyone with a credit card. I hope your credit card company is watching out for you but if not, definitely watch out for yourself.
