How are u paying for it? If credit card, stop it through your credit card company. If debit card, have them do a chargeback on it, and see if yahoo responds then. That's what I had to do with AOL. I used my card, I actually closed out my card, told them to hot card, and then they did charge backs. If u pay direct debit from a checking account, do a stop by. They can find the authorization number and do a ACH stop pay on it. I'd worry about stopping payment, because if they aren't getting the money, yahoo will finally maybe cancel it.
