So today I check my credit card statement online and see that EW billed me $24.95 for a year's subscription. Luckily there was a phone number posted with the statement so I called and I'm thankful to say that the sales rep was extremely nice and credited my VISA and didn't even ask me why or try to sell me anything.
Still, I'm cheesed off that they'd charge my card without my authorization. If they hadn't assured me they'd credit my account I'd have insisted on it.
