There are always ways to steal a CC number. One of the simplest is when you pay by CC at a restaurant, the server just snaps a picture when she goes out back to process it.
There are to many to list.
The last time my CC was compromised, I received a text, email, and phone call from the company. I called them back immediately and confirmed that the $500.00 worth of tickets for some concert were not paid for by me.
The card was immediately cancelled and replacements overnighted to me. At first the customer service rep said it would be 7-10 days before I got the replacements. I mentioned that I was going on vacation in two days and if they couldn't get the cards to me in time, I'd just have to use their competitor's card.
The worst experience I had was with Discover, which is why I won't use them any more. My card was compromised in late June. THEY didn't figure it out, I did because I got a call from Walmart.com asking me to verify some purchases. Nope, not me.
I called Discover right away and reported the compromise. They said that they'd get the cards out to me in a week or so. I said I'd prefer if they got them to me sooner since we were going to New York for a friend's wedding. Sure, not problem, they said No problem, and no card either.
I called them back and asked what happened. This time I was told they couldn't send them out overnight because of "company policy." An escalation to the supervisor and I was told that they could get them out in three days and they'd be in my mall box on July 4. I explained that in America, that's kind of a big holiday. Used my back up CC on the trip and applied for a Visa.
The day the Visa came in the mail, I called Discover and told them to close the account. A week later I got a call from "customer retention" asking why I did that. I told him the story and he apologized for the screw up.
"What can we do to fix this?"
"Send me a check for $1,000.00."
"Uh, we can't do that."
"Goodbye."
Just so you don't think that I flew off the handle, this was the third time in less than a year that my Discover Card was compromised. It's a real PITA to change the autopay accounts I have set up every time.
