I'm starting to get really ticked at my bank. It seems like every time I make more than a couple of purchases with my card in a day- even from places I commonly buy from, they lock my card. In the past, they've left me totally stranded without access to cash while I was travelling. Lately, they've been able to unlock my card when I call to complain, but it's still annoying. I know fraud detection is important, but I'm starting to think my bank is really dumb for nailing me three times now for my own normal use of my own money. Does anyone have a good story about how their bank has saved them from untold heartache because they were savvy enough to catch card fraud?
