Hi,
Yesterday i purchased Windows for $49.98 by using my Visa credit card which marked as MasterCard. (I clicked MasterCard button by mistake) It's odd but purchase completed.
After i checked my account and no charge appeared then.
Today i made a new purchase (i clicked as VISA this time) and i found my card account charged twice !!! (Charge is not completed yet , always there is 2-3 days delay, as i live in Europe)
My question is, how i can cancel my first purchase ? (I have all data necessary as account numbers etc.)
Sorry for my English, and thanks in advance for any help.
