They billed you thru your ISP? That's the 1st time I've ever heard of that happening. Well, yes get in touch with your ISP & tell them it was a fraud/scam & that you are going to report that site to the authorities & ask your ISP to cancel the transaction. Did you locate the original site you paid the money to? If you see the last link I left, at the top of the page is a link where you can report that site. Do it so others won't get caught by them. From what I can remember, your scam episode is the most expensive I've heard of.
