Hi! I I recently bought an in-app purchase but unfortunately my credit card thatI used has an unpaid balance. Now when I try to update apps the app store says " Verification Required. Tap to continue and sign in to view billing information".

Hi! I I recently bought an in-app purchase but unfortunately my credit card that I used has an unpaid balance. Now when I try to update apps the app store says " Verification Required. Tap to continue and sign in to view billing information". Now I can't update or install even free apps it's either I pay my card's balance or use a different card. Question is now I change my mind about the in-app purchase how can I cancel the purchase so I can update other apps and/or download other free apps? Thanks!
