I use credit cards a lot, but keep all the receipts and review my bills carefully. I haven't found many problems, but there were two notable ones: a $160 charge on my Nordstrom bill for size 2 pants (I used to be thin, but was NEVER a size 2!), and the $100 charge to an Internet porn site. Both were taken care of quickly and efficiently, but it is a very unseemly feeling! Not to mention the inconvenience of having to cancel the card and wait for a new one.
Vibes to Elmore for a quick and painless resolution!
