There's no way that I normally would have made an eleven cent credit card transaction. I googled the number, and found literally hundreds of reports of people saying that they had a small-denomination fraudulent transaction tied to this phone number. My guess is that someone got a bunch of credit card numbers and tried to slip under the radar by billing them only a very tiny amount.
I've disputed the charge, although it's going to cost me more to do that than to pay it. Sigh.
