Purchase cancelled from Google Play Store, but verification fee deducted

Yesterday I was trying to purchase an app from the Play Store. So I added my card details to the dialog window that appeared, and Google deducted a small sum from my A/C (Rs.51 INR), which I know, is for the purpose of verification of my card. But the problem is, the app which I was trying to purchase says the transaction was cancelled. Here's the transaction log from Google Payments : > Sep 1 » Google has canceled this purchase. > > Comments from Google: Your credit card ending in XXXX was declined. > > Please select a different payment method. > > Sep 1 » Your XXXX-XXXX was declined for this purchase. If I entered wrong credentials, then why did the verification amount got successfully deducted? Should I attempt to make the purchase again?
